Question

If all the organisms of one trophic level in a food chain die, what would be its impact on the population of organisms in other trophic levels? It will

a) remain the same in the next trophic level

b) increase in the next trophic level

c) increase in the lower trophic level

d) remain the same in the lower trophic level

Answer 1

Correct answer is (c) increase in the lower trophic level

Explanation: If all the organisms of one trophic level in a food chain die, the population of organisms in the lower trophic level will increase. This is because there will be no predators to eat them. For example, if all the rabbits in a food chain die, the population of grass will increase because there will be no rabbits to eat it.
