Which one is NOT correctly matched?

Options

  1. AProductivity - rate of biomass production
  2. BGross primary productivity - photoautotrophs
  3. CNet primary productivity - available biomass for consumption
  4. DSecondary productivity - formation of new organic matter in producer

Correct answer

D. Secondary productivity - formation of new organic matter in producer

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. The rate of assimilation of food energy by consumers is called secondary productivity and this energy is available to carnivores as they are the consumers.
