Answer:
D) molecules diffuse through transport proteins.
Answer:
1. Plants utilize some of the incoming energy derived from photosynthesis for their own self-maintenance.
3. Plants and algae carry out both photosynthesis and cellular respiration.
5. Plants, algae, and cyanobacteria utilize light energy from the sun into their own biomass.
Explanation:
The gross primary productivity (GPP) of an ecosystem represents the rate at which the solar energy is captured during photosynthesis in a given period. Producers (plants, algae and cyanobacteria) perform cellular respiration to provide energy for their life processes. Cellular respiration consumes part of the total photosynthetic output. The energy available in tissues of producers after cellular respiration is called net primary productivity (NPP).
Therefore, NPP is the amount of biomass or the energy stored in the tissues of the producers for growth after cellular respiration for their normal daily activities and self-maintenance. So, NPP is always less than GPP.
