Trend Analysis of the Environment Biodiversity MCQs in UPSC prelim exams?

UPSC Prelim-2021 Answerkey Topicwise Analysis

Environment in Prelims-2019 and before Prelim-2020: Continuity and Change Prelims-2021
– 2018: 3 Easy, while the rest of the environment MCQs were in the medium to tough category.

– 2019: same as above

– only 1 easy out of 15 MCQs, rest is environment MCQs were medium to tough – 6 easy out of 20 MCQS, rest is medium to tough.
Ever since the merger of forest service prelims with Indian civil services (IAS/IPS) prelims, UPSC had been devoting about 1/5th of the Prelim paper-1 to environment, biodiversity topics but in 2017 and 2018 less number of questions were asked. same scene, but more so, to make space for a large number of agriculture questions. 1/5 of the paper is dedicated to environment just like the scene in 2016 and 2019.
Traditional preparation sources giving decreasing utility in Prelims

– ShankarIAS book could solve just 2-2 MCQs in 2018 and 2019’s prelims.

– India Yearbook: 0 MCQ (2017), 1 MCQ (2018), 0 MCQ (2019)

– hardly 1-2 MCQs from NCERT, NIOS type textbooks.

– No question could be solved from Shankar or IYB.

– NIOS helped only in ’50:50′ elimination of some MCQs. but no direct answers.

– Two questions could be solved from Shankar

– six MCQs from NCERT

– Before 2019: questions from the ‘About us’ websites of obscure International organisations and funds – TEEB, CCAC, GCCA, PAGE, GACSA, Biocarbon fund, Forest carbon facility, birdlife international etc.

– But this nonsense was stopped in 2019.

– Thankfully no random question from “About us” pages of low-profile bodies. – The lunacy regarding “About us” pages returns with New York declaration on Forest, R2  practices, Watercredit, Common carbon metric et cetera questions
2-3 questions from flora-fauna. same Examiner gone crazier than usual with regarding flora fauna 9 out of 20 questions are dedicated to it! 😰😰
Wildlife Park and Sanctuary related questions are asked from obscure and contrived angles. They’re never easy. Same sadistic game is continued. Instead of focusing on individual parks and sanctuaries, this time focused on forest types and biomes in general
Usually a few questions on R&D such as fuel cell, bio toilets, bioremediation, algae fuel, carbon sequester, H-CNG, Remote Sensing etc. Seems all that R&D quota of MCQs were exhausted in the science tech and agriculture portion of the Prelims-2020 Paper. Nothing left to ask here, in the environment. Some environmental chemistry type questions from copper smelting furnace oil etc, but Relatively less lunatic than 2020
pollution  / water conversation = was the single largest sub-topic asked within Environment in 2018 and 2019. Pollution-Prem continues. 7 out of the 15 MCQs devoted to pollution  / water conversation. Pollution is second largest topic of this time within environment (after Flora fauna).
  • Large number of environment MCQs had 3 statements / more, then you had to find which of them were correct= very lengthy and mentally taxing paper.
  • To conclude, the environment section is medium to tough. But, it feels ‘monotonous’ because excessive MCQs just require you to know about flora-fauna/ species. In Previous years, UPSC examiners ensured that there was an internal ‘variety’ of MCQs/topics within a subject.

How to prepare Environment and biodiversity for Prelims – 2022?

  • For detailed strategy and booklist, refer to Mrunal’s UPSC Roadmap-2022 lecture with UPSC Topper Rank#2: Jagrati Awasthi. 🔖Unlock Free content with Code: ‘Mrunal.org’
  • To cultivate the logical elimination 50:50 skill, You must have strong foundation in environment. So avoid mentality- that why waste time/money on NCERT/NIOS when no direct questions are coming. You should prepare them irrespectively.
  • (Optional) ShankarIAS Environment Book (6th Ed) as base-book for advanced theories and contemporary issues on environment. Yes, relatively less MCQs came from here in 2019 and 2020 and 2021
    • OR you may even refer to free PDF compilations by various coaching institutes regarding the environment segment.
  • Essential of ecology by Colin Townsend – around 7 out of 20 questions on environment could be solved from this. There were some questions directly lifted from the paragraphs of this book. But I hesitate recommending this for following reasons:
    • Some MCQs overlap with NCERT / NIOS/ GCL.
    • No guarantee of repeat success NEXT exam.
    • Very expensive academic book. Imported version costing nearly ₹10,000
  • (When it is published next year) India Yearbook 2022 by Ministry of information and Broadcasting: Ch. 12 on Environment and Ch.1 on Land and People. There is no need to actually buy it because plenty of free summaries will be released by e-learning website
  • Selective Study any one “base-book” on Indian Geography: Majid Husain | हिंदी में भी उपलब्ध ch. 1, 2, 3, 4 and 5.
    • Some of the flora-fauna / park-sanctuary questions require background knowledge of weather/climate/elevation/drainage so you need command over geography as well.
  • Selective study of the State of Forest Report
  • To keep the paper tough, UPSC examiner even lifts statements from bare acts and rules but if you engage in preparing those things, it’ll give poor cost:benefit.
  • In 2019, few questions were ‘National Geographic Kids GK’ like viviparous snakes & herbivore turtles. It’s futile to make a compilation of such wildlife GK, because UPSC examiner can always ask something random or technical that only an IFS (Forest) candidate with B.Sc (Agriculture / Zoology / Botany) can attempt it. Remember that some questions are meant to test the Forest Service candidates. UPSC examiner is not mandating you, as a non-IFS aspirant, must have impeccable command over zoology and botany.
  • In 2020, similarly excessive focus on flora-fauna-parks. But beyond a point, it gives poor cost benefit in investing your time in this.
  • For Current Affairs: IndianExpress OR Hindu, and whichever PDF compilation you like/ feel comfortable with.
    • Focus should be on the CA related to Pollution, Clean Energy, New legal amendments, SC/NGT Judgement, international treaties, funds, R&D, reports-rankings.
  • For Contemporary Affairs: In the environment segment the focus of UPSC examinations on contemporary office usually after a lag of one to two years. So, accordingly for Prelims-2021 you should prepare environment topics that were in news during 1/1/2019 from any ONE (free) PDF compilations you like. Don’t try to be Half-Blood-Prince, “I’ll make super-secret notes by compiling all Environment CA-PDF from VisionIAS, IASparliament and 5 other sources. because even in the best case scenario such compilation will only help you arrive at 50:50 elimination stage.

Answerkey: Environment questions asked in UPSC Prelims 2021

Let’s solve the Environment and biodiversity questions that were asked in the latest UPSC Prelims!

Flora Fauna Organisms 


[CSP21-SET-C] Q.76)  Which one of the following is a filter feeder?

  1. Catfish
  2. Octopus
  3. Oyster
  4. Pelican

Difficulty : Medium to Tough🥵

Type: Theory 📚 

Explanation:

  • Filter feeding, in zoology, a form of food procurement in which food particles or small organisms are randomly strained from water.
  • Oysters like other shellfish have unique filter-feeding ability, in the sense it takes in water through its gills, which then filters it for nutrients like suspended fragments of plankton, while automatically draining out the rest of the water.

[CSP21-SET-C] Q.71)  Which one of the following is used in preparing a natural mosquito repellent?

  1. Congress grass 
  2. Elephant grass
  3. Lemongrass
  4. Nut grass

Difficulty : Medium to Tough🥵

Type: Theory 📚

Explanation:

  • You could apply some logic that to act as mosquito repellent the grass needs to have an aromatic smell. So Elephant grass could not be the answer and lemongrass may have been the answer. 
  • Lemongrass leaves are the most commonly found plants found in India. You can use lemongrass oil or can crush the leaves and then applying the oily mixture directly to the skin. Therefore, Correct Answer is “C”.

[CSP21-SET-C] Q.72)  Consider the following kinds of organisms: 

  1. Copepods
  2. Cyanobacteria 
  3. Diatoms
  4. Foraminifera

Which of the above are primary producers in the food chains of oceans?

  1. 1 and 2 
  2. 2 and 3 
  3. 3 and 4 
  4. 1 and 4 

Difficulty : Medium🧐 Depending on your preparation of environment and oceanography.

Type: Theory 📚

Explanation:

  • Diatoms are found in fresh water as well as in marine environments. They are microscopic and float passively in water currents (plankton).  Most of them are photosynthetic. Diatoms are the chief ‘producers’ in the oceans.  → #3 is right. We are 50:50 between B or C. 
  • Cyanobacteria (also referred to as blue-green algae) have chlorophyll, similar to green plants and are photosynthetic autotrophs.  #2 is right.
  • Therefore correct answer B] 2 and 3.

[CSP21-SET-C] Q.90)  In the nature, which of the following is/are most likely to be found surviving on a surface without soil?

  1. Fern
  2. Lichen
  3. Moss
  4. Mushroom

Select the correct answer using the code given below

  1. 1 and 4 Only
  2. 2 Only
  3. 2 and 3
  4. 1, 3 and 4

Difficulty :Tough🥵 Depending on which chapter of NCERT book you are reading, you may arrive at different answer.

Type: Theory 📚

Explanation:

  • Since mosses form dense mats on the soil, they reduce the impact of falling rain and prevent soil erosion → #3 is wrong. we are 50:50 between A or B. Everything now depends on the validity of statement#2.
  • Lichens (#2) grow on any undisturbed surface–bark, wood, mosses, rock, soil, peat, glass, metal, plastic, and even cloth.ichens can absorb water through any part of their thalli and have no need of roots. According to, Pennsylvania University article
  • Land without soil can support only very small primitive plants such as lichens and mosses that can cling onto a rock surface, says the book Essentials of Ecology Third Edition, 3rd Edition. So, Answer should be “C”: 2 and 3.

[CSP21-SET-C] Q.78)  Which of the following are detritivores?

  1. Earthworms
  2. Jellyfish
  3. Millipedes
  4. Seahorses
  5. Woodlice

Select the correct answer using the code given below.

  1. 1, 2 and 4 Only
  2. 2, 3, 4 and 5 Only
  3. 1, 3 and 5 Only
  4. 1, 2, 3, 4 and 5

Difficulty : Medium🧐 by elimination.

Type: Theory 📚

Explanation:

  • Detritivores (e.g., earthworm) break down detritus into smaller particles. This process is called fragmentation. Detritus consists of dead plant remains and dead remains of animals. #1 is wrong. And if earthworm belong to this group then jellyfish (#2) and seahorse (#4) cannot be part of this group. Thus A, B and D are eliminated & we are left with correct Option “C”
  • Alternatively you could apply some logic that earthworm and woodlice look like insects whereas Jellyfish and seahorses live in sea so 2 and 4 are ‘odd men’ so eliminate them.

  1. Cnidarians
  2. Fungi
  3. Protozoa

Select the correct answer using the codes given below.

  1. 1 and 2 Only
  2. 2 and 3 Only
  3. 1 and 3 Only
  4. 1, 2 and 3

Difficulty : Tough🥵 requires knowledge of class 11-12 NCERT Biology and you can’t arrive at final answer until you know what is Cnidarians?

Type: Theory 📚 

Explanation:

  • Lichens:  Lichens  are  symbiotic  associations. Algae prepare food for fungi and fungi provide shelter and absorb mineral nutrients and water for its partner. So close is their association that if one saw a lichen in nature one would never imagine that they had two different organisms within them.  → #2 is right. 
  • CNIDARIA: Some of these species live in colonies (corals), while others have a solitary like–span (Hydra). Coral exhibit symbiosis with Algae. So, #1 is right.
  • NCERT Class11: “All protozoans are heterotrophs and live as predators or parasites.” If they live as parasites then symbiosis difficult. So, #3 is wrong. → Therefore, Correct Answer is “A” only 1 and 2.
  • Some webpages say that termites have a symbiotic relationship with protozoa that live in the termite’s gut → #3 is correct so answer is “D”] Only 1 and 2 and 3. 
  • Final Answer A or D? Have to wait for the UPSC Official Answer Key.

To reduce the chance of being captured by predators, which of the above organisms rolls up/roll up and protects/ protect its/their vulnerable parts?

  1. 1 and 2 
  2. 2 only
  3. 3 only
  4. 1 and 3

Difficulty : Medium🧐 to Tough🥵

Type: Theory 📚 

Explanation:

  • Hedgehogs have a coat of stiff, sharp spines. If attacked they will curl into a prickly and unappetizing ball that deters most predators. Option #1 is correct. We are 50:50 between A or D. 
  • A startled pangolin will cover its head with its front legs, exposing its scales to any potential predator. If touched or grabbed it will roll up completely into a ball, while the sharp scales on the tail can be used to lash out. Option #3 is correct.
  • Therefore, correct answer is “D”: 1 and 3
  • Marmots live in burrows and hide themselves in holes when there is a predator. Option #2 is incorrect.

  2. b) 4 and 5
  3. c) 2, 3 and 4
  4. d) 1, 3 and 5

Difficulty :Medium🧐 to Tough🥵

Type: Theory 📚 

Explanation:

  • NIOS Environment: Page 97-98: Grasslands occur in both tropical and temperate regions where rainfall is not enough to support the growth of trees. So, #4 is right. we are 50:50 between B or C.
  • The vegetation of savanna characteristically consists of grassland with scattered small trees, but extensive areas have no trees.  In some savannas, herds of grazing herbivores have a profound influence on the vegetation, favoring grasses (which protect their embryonic, actively dividing tissues in buds at or just below ground level) and hindering the regeneration of trees (because these same tissues are exposed to browsing animals and to fire).  → #3 is right. 
  • Fire, whether natural or human-induced, can be a common hazard in the dry season.  → #2 is right.
  • So final answer: c) 2, 3 and 4
