Select the INCORRECT match from the following.

Options

  1. APrimary productivity = amount of organic matter produced per unit area by photosynthesis
  2. BProductivity = The rate of biomass production
  3. CNet primary productivity = G P P - R
  4. DGross primary productivity = rate of formation of new organic matter by consumers

Correct answer

D. Gross primary productivity = rate of formation of new organic matter by consumers

Step-by-step solution

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. The rate of assimilation of food energy by consumers is called secondary producti
