Question

What will happen if instead of 20,000 we have 100,000 species of frogs on Earth?

(a) Little threat to the ecosystem

(b) Serious threat to the safety of the ecosystem

(c) Ecosystem remains unchanged

(d) No threat to the ecosystem

I got this question in an internship interview.

I want to ask this question from Importance of Species Diversity to the Ecosystem topic in chapter Biodiversity and Conservation of Biology – Class 12

Answer 1

The correct answer is (b) Serious threat to the safety of the ecosystem

Easiest explanation: An ecosystem consists of biotic and abiotic components that interact within a system. If there is an increase in the number of frog species, the prey (food that frogs eat) might become extinct and so will the other prey-predator species causing serious harm to the safety of the ecosystem.
