The available biomass for the consumption, to heterotrophs is ----------------.
Options
- AGross primary productivity
- BNet primary productivity
- CSecondary productivity
- DNet secondary productivity
Correct answer
B. Net primary productivity
Step-by-step solution
Gross primary productivity (GPP) is the total rate of photosynthesis or total biomass produced by primary producers.
A considerable amount of GPP is utilized by plants in respiration (R).
Net primary productivity (NPP) is the gross primary productivity minus respiration losses (NPP = GPP - R).
NPP is the available biomass for the consumption to heterotrophs (herbivores and decomposers).
Answer: Net primary productivity
A considerable amount of GPP is utilized by plants in respiration (R).
Net primary productivity (NPP) is the gross primary productivity minus respiration losses (NPP = GPP - R).
NPP is the available biomass for the consumption to heterotrophs (herbivores and decomposers).
