Question

Primary productivity is defined as(1 point)

the rate that plants and other photosynthetic organisms produce organic compounds.

the adjusted amount of energy in an ecosystem due to energy use by organisms for respiration.

the process where green plants and some other organisms convert light energy into chemical energy using carbon dioxide and water.

the overall amount of energy captured by plants and other photosynthetic organisms by the chloroplast.

Answer 1

the rate that plants and other photosynthetic organisms produce organic compounds.

(Primary productivity = rate of biomass/organic matter production by autotrophs. Net and gross productivity differ by respiration.)
