The right answer is B

A primary producer corresponds, in an ecosystem, to an autotrophic living being, that is to say capable of producing organic matter from mineral matter. It is the first element of the food chain. This organism is totally or partially ingested by a primary consumer, itself being the potential target of secondary consumers.

Decomposers are living creatures that contribute to the degradation of dead organic matter or feces by returning them in mineral form. They play a crucial role in an ecosystem because they participate in the recycling of the elements.
