What is the difference between Gross Primary Productivity (GPP) and Net Primary Productivity (NPP)?(1 point)

Responses

NPP is the amount of organic material produced by photosynthesis, while GPP is the amount of organic material not used for respiration, therefor available to the next trophic level.

The correct response is:

GPP is the amount of organic material produced by photosynthesis, while NPP is the amount of organic material not used for respiration, therefore available to the next trophic level.

Gross Primary Productivity (GPP) refers to the total amount of organic material produced by photosynthesis in a given area over a specific time period. Net Primary Productivity (NPP) is the amount of organic material that remains after accounting for the energy used by producers for respiration; it represents the energy available to the next trophic level.
