Question

In a grassland ecosystem, which trophic level has the greatest biomass?

• A. Producers
• B. Primary consumers
• C. Secondary consumers
• D. Tertiary consumers
• E. Decomposers

Answer 1

Answer: (A)

Producers

A. Producers are the green plants that capture light energy and convert it into chemical energy by the process of photosynthesis.

B. Primary consumers are the herbivores that feed on producers.

C. Secondary consumers are the carnivores that feed on primary consumers and producers.

D. Tertiary consumers are the animals that feed on primary and secondary consumers and producers.

E. Decomposers are the microorganism that break down organic material.

Since biomass is the amount of living matter or organic matter present in an ecosystem, producers have the greatest biomass since they perform photosynthesis.

So, the correct answer is 'Producers'.
