The rate of conversion of light energy into the chemical energy of organic molecules in an ecosystem is called

Options

  1. AGross primary productivity
  2. BNet primary productivity
  3. CNet secondary productivity
  4. DGross secondary productivity

Correct answer

A. Gross primary productivity

Step-by-step solution

The amount of matter found in the organism is called biomass. Gross primary production (GPP) is the rate at which an ecosystem's producers capture and store a given amount of chemical energy as biomass in a given length of time. (Definition). It is also the rate of conversion of light energy to chemical energy by producers in an ecosystem. Total production of organic matter is called gross primary productivity and the energy left after utilization of producers is termed net primary productivity. Community productiv
