Which Environment and Ecology term is correctly identified by “biotic and abiotic components interact within it” and “energy flows while nutrients cycle through the system”?

Correct Answer: Option B — Ecosystem. Ecosystem is correct because it is biotic and abiotic components interact within it. Ecosystem is also specifically associated with energy flows while nutrients cycle through the system. Two additional identifying facts are that Ecosystem is energy flows while nutrients cycle through the system and Ecosystem is associated with a pond, forest or grassland can be studied as an ecosystem. Why the other options are incorrect: • Option A — Food Chain: Food Chain is producers form the base of most grazing food chains. • Option C — Biodiversity Hotspot: Biodiversity Hotspot is the concept prioritizes globally important conservation regions. It is incorrect here because its separate identifying association is parts of the Himalaya and Western Ghats-Sri Lanka hotspots occur in India. • Option D — Wetland: Wetland is marshes, floodplains, lakeshores and mangrove areas can be wetlands. It is incorrect here because its separate identifying association is wetlands can store floodwater and support specialized biodiversity. Exam Takeaway: Connect Ecosystem with “biotic and abiotic components interact within it” and “energy flows while nutrients cycle through the system”.
