Question

Which organismal category is responsible for producing primary productivity in ecosystems?

Options

• Consumers (Heterotrophs)

• Parasites

• Decomposers

• Producers (Autotrophs)

Answer 1

Primary productivity is exclusively produced by autotrophic organisms (producers), primarily plants and photosynthetic microorganisms. These organisms synthesize organic matter through photosynthesis, capturing light energy and converting it into chemical energy stored in biomass.
