Question

Which of the following components of an ecosystem has the greatest biomass?

Options

• Primary producers

• Primary consumers

• Secondary consumers

• Decomposers

Answer 1

Primary producers

Explanation:

In most ecosystems, primary producers have the greatest biomass because they create organic material through photosynthesis, serving as the base of the food chain. Their biomass supports all other trophic levels, as consumers depend on producers for energy. Hence, primary producers form the largest biomass component in an ecosystem.
