Ans 1: (Master Answer)
A
In the given food chain grass is eaten by grasshopper. Grasshoppers are eaten by frogs; Frogs are eaten by snakes, and snakes are eaten by peacocks. If frog is completely removed from the given food chain, then no-one will eat the grasshopper, so the population of grasshoppers will increase.Since frog is completely removed, Snakes will not have enough food to eat, so population of snakes will decline. Hence b and d are correct and option A is the right answer.
