If tigers are seen in an area, why is this single clue not enough to prove that ecology is healthy?

Answer and explanation

Correct answer: Because the presence of tigers alone does not reveal the overall condition of prey, water, vegetation and habitat.

Tigers are apex predators, so their presence can be an important sign, but it cannot by itself prove that the whole ecosystem is healthy. A healthy ecosystem also needs adequate prey, water sources, suitable vegetation, secure habitat and balance among other organisms. Option B is wrong because tigers coexist with many other organisms. Exam tip: assess ecosystem health using several biotic and abiotic indicators together.
