Question

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

• A. Primary producers
• B. Primary consumers
• C. Secondary consumers
• D. Decomposers

Answer 1

The correct option is A Primary producers

The biomass is the mass of living biological organisms in a given area or ecosystem at a given time. The mass can be expressed as the average mass per unit area, or as the total mass in the community. An ecological pyramid is a graphical representation that shows, for a given ecosystem, the relationship between biomass or biological productivity and trophic levels. The bottom of the pyramid represents the primary producers (autotrophs). The primary producers take energy from the environment in the form of sunlight or inorganic chemicals and use it to create energy-rich molecules such as carbohydrates.

So the correct option is 'primary producers'.
