Every question carries a verified answer key with a plain-English explanation, so you learn the exact fact — not just the correct option. Attempt all 15 in about 12 minutes, then use the score bands to decide your next revision step.

Why Environment Questions Matter in UPSC, SSC and Banking Exams

Environment and ecology has become a high-weightage segment after 2011, when UPSC revamped its Prelims pattern. Typically 10–20 questions combine environment and geography each year, and several environment questions overlap with current affairs — a Ramsar site addition, a COP summit outcome or a new tiger reserve can appear directly in the paper.

For SSC CGL and Banking exams, environment questions are usually simpler and fact-based: conventions and their years, pollution-control bodies, national parks and recent government schemes. That makes this section one of the fastest-scoring areas if you prepare from PYQs and a good current affairs digest.

• UPSC Prelims: Analytical ecology questions — food chains, pyramids, species behaviour — plus convention-linked current affairs.
• SSC CGL/CHSL: Direct facts — Ramsar sites, Project Tiger, Acts and their years.
• Banking (IBPS/SBI): Static GK plus recent environment news in the General Awareness section.

Quiz Instructions and Exam Pattern

• Total questions: 15 MCQs, 1 mark each.
• Suggested time: 12 minutes — roughly 45 seconds per question, matching Prelims pace.
• Negative marking: For UPSC practice, deduct 0.66 marks for each wrong answer; for SSC/Banking practice, deduct 0.25 marks.
• Attempt all questions before scrolling to the answer key — honest self-testing is the whole point.

(a) 40% (b) 50% (c) 60% (d) 75%

Detailed Answer Key with Explanations

1. Q1 — (b). Grass → Grasshopper → Frog → Snake → Hawk. Producers (grass) come first, followed by primary consumers and successive predators. This is a classic PYQ-level food chain question.
2. Q2 — (c). The pyramid of energy is always upright because energy is lost at each trophic level (10% law). Pyramids of number and biomass can be inverted (e.g., tree-based number pyramids; lake biomass pyramids).
3. Q3 — (b). Keystone species — e.g., the sea otter in kelp ecosystems — have an outsized ecological effect relative to their numbers.
4. Q4 — (d). A UNESCO biosphere reserve tag is not a hotspot criterion. Hotspots need at least 1,500 endemic vascular plant species and 70%+ habitat loss. India has four biodiversity hotspots: the Himalayas, Western Ghats–Sri Lanka, Indo-Burma and Sundaland.
5. Q5 — (b). The Western Ghats qualify due to exceptional plant endemism combined with severe habitat threat.
6. Q6 — (b). Project Tiger launched in 1973 from Jim Corbett National Park. (The Wildlife Protection Act was 1972 — a common trap option.)
7. Q7 — (b). The Nilgiri Biosphere Reserve (1986) was India’s first and is part of UNESCO’s Man and Biosphere (MAB) network.
8. Q8 — (b). Ramsar designation rests on international significance, particularly as waterfowl habitat, under the criteria of the 1971 Ramsar Convention.
9. Q9 — (b). The UNFCCC was adopted at the Rio Earth Summit, 1992; it entered into force in 1994. Kyoto (1997) set binding targets on developed countries.
10. Q10 — (c). The Paris Agreement (2015, effective 2016) set the “well below 2°C, pursue 1.5°C” goal and works through voluntary NDCs.
11. Q11 — (b). The Montreal Protocol phases out ozone-depleting substances; its Kigali Amendment (2016) addresses HFCs, a frequent current-affairs angle.
12. Q12 — (b). NGT is a statutory body under the NGT Act, 2010, mandated to dispose of environmental cases within six months of filing.
13. Q13 — (c). The CPCB was first constituted under the Water Act, 1974; it later received powers under the Air Act, 1981 and the Environment (Protection) Act, 1986.
14. Q14 — (c). India’s Ramsar network crossed 85 sites, among the largest in Asia. Verify the exact current number before your exam, as designations continue.
15. Q15 — (b). India’s updated NDC (2022) targets about 50% of cumulative electric power installed capacity from non-fossil fuel sources by 2030, alongside the net-zero-by-2070 pledge announced at COP26 Glasgow.

Frequently Asked Questions

Q: How many environment questions appear in UPSC Prelims every year?

Typically 10–20 questions combine environment and geography, though the trend varies year to year. Some papers lean heavily on ecology concepts; others mix in convention-linked current affairs, so prepare both static and dynamic content.

Q: What is the Ramsar Convention and which Indian sites are famous?

The Ramsar Convention (1971, Ramsar, Iran) is an intergovernmental treaty for the conservation and wise use of wetlands. India’s most famous Ramsar sites include Chilika Lake (Odisha) and Keoladeo National Park (Rajasthan) — India’s first two, designated in 1981 — plus the Sundarbans Wetland, Loktak Lake and Wular Lake.

Q: Which is the best source for environment MCQ practice?

NCERT Biology (Classes 11–12) for concepts, PYQs from UPSC and SSC papers for pattern and difficulty, and monthly current affairs compilations for Ramsar additions, COP outcomes and new protected areas. Cross-check announcements on PIB.

Q: What is the difference between the Kyoto Protocol and the Paris Agreement?

Kyoto (1997) imposed binding emission-reduction targets only on developed nations. The Paris Agreement (2015) moved to a bottom-up model where all countries set voluntary NDCs, with the collective goal of limiting warming well below 2°C.

Q: What role does the NGT play in pollution control in India?

The NGT is a statutory body under the NGT Act, 2010, set up for fast disposal of environmental cases — with a mandate to conclude cases within six months. It can award compensation for environmental damage and order closure of polluting units.
