Environment and Ecology Questions and Answers

Correct Answer: Option D — Environmental Impact Assessment. Environmental Impact Assessment is correct because it is monitoring helps compare actual outcomes with commitments. Environmental Impact Assessment is also specifically associated with baseline conditions and predicted impacts are assessed. Two additional identifying facts are that Environmental Impact Assessment is mitigation and environmental-management measures are considered and Environmental Impact Assessment is associated with monitoring helps compare actual outcomes with commitments. Why the other options are incorrect: • Option A — Ecosystem: Ecosystem is a pond, forest or grassland can be studied as an ecosystem. It is incorrect here because its separate identifying association is biotic and abiotic components interact within it. • Option B — Food Chain: Food Chain is interconnected food chains form a food web. It is incorrect here because its separate identifying association is producers form the base of most grazing food chains. • Option C — Biodiversity Hotspot: Biodiversity Hotspot is a hotspot is not simply any place with many species. Exam Takeaway: Connect Environmental Impact Assessment with “monitoring helps compare actual outcomes with commitments” and “baseline conditions and predicted impacts are assessed”.

Correct Answer: Option C — Environmental Impact Assessment. Environmental Impact Assessment is correct because it is mitigation and environmental-management measures are considered. Environmental Impact Assessment is also specifically associated with a process for examining likely environmental effects before project decisions. Two additional identifying facts are that Environmental Impact Assessment is mitigation and environmental-management measures are considered and Environmental Impact Assessment is associated with monitoring helps compare actual outcomes with commitments. Why the other options are incorrect: • Option A — Ecosystem: Ecosystem is energy flows while nutrients cycle through the system. It is incorrect here because its separate identifying association is a functional unit of organisms and their physical environment. • Option B — Food Chain: Food Chain is consumers occupy successive trophic levels. It is incorrect here because its separate identifying association is a linear sequence showing transfer of food energy. • Option D — Biodiversity Hotspot: Biodiversity Hotspot is parts of the Himalaya and Western Ghats-Sri Lanka hotspots occur in India. Exam Takeaway: Connect Environmental Impact Assessment with “mitigation and environmental-management measures are considered” and “a process for examining likely environmental effects before project decisions”.

Correct Answer: Option D — Wetland. Wetland is correct because it is the Ramsar Convention provides an international wetland framework. Wetland is also specifically associated with marshes, floodplains, lakeshores and mangrove areas can be wetlands. Two additional identifying facts are that Wetland is wetlands can store floodwater and support specialized biodiversity and Wetland is associated with the Ramsar Convention provides an international wetland framework. Why the other options are incorrect: • Option A — Environmental Impact Assessment: Environmental Impact Assessment is monitoring helps compare actual outcomes with commitments.
