Question

What will happen if the lions are removed from the following food chain. Grass→deer→Lion

Answer 1

The removal of lions from the 'food chain' Grass-Deer-Lion would lead to an increase in the population of the deer.

EXPLANATION:

The population of deer would grow to such an 'extent' that they would eat up all the grass available. This would lead to a decrease in the density of grass and would turn most of the land into a desert area. This would in turn make the survival of a lot of species difficult.
