Question

primary productivity is not limited by ________. a. the availability of sunlight b. time c. the availability of nutrients d. access to water please select the best answer from the choices provided

Explanation:

Primary productivity refers to the rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances. Sunlight is needed for photosynthesis (in most primary producers like plants), nutrients are essential for growth and metabolic processes, and water is a reactant in photosynthesis (for photo - autotrophs). Time is a measure of the duration over which processes occur but is not a limiting factor in the sense of being a resource that is consumed or in short supply for primary productivity.

Answer:

B. time
