Question: What will happen if all the deers are killed in the given food chain?

Grass — Deer — Lion


a. The population of Lion increases
b. The population of grass decreases
c. The population of Lion decreases and grass increases
d. The population of Lion remains unchanged

Answer:
Answer: (c)

If all the deer are killed in the given food chain, there won’t be any food available for the lions. Hence, the lions will starve to death and their population will decrease. On the other hand, there won’t be any consumers of grass hence, its population would increase.
