Question

The energy flow in an ecosystem is based on the primary productivity of autotrophs.

• A. True
• B. False

Answer 1

The correct option is A True

Primary production is defined as the rate of biomass or organic matter produced per unit area over a time period by plants during photosynthesis. Plants are autotrophs because they produce their own food using light, water and carbon dioxide. It is the producers (plants) which are the prime source of chemical energy in the ecosystem. They convert solar energy into chemical energy and transfer it to the successive level of organisms in a food chain.
