Explain how the activities of autotrophs and heterotrophs enable the flow of energy within an ecosystem.

Stage 1: Organic monomers evolved from inorganic compounds.

Stage 2: Organic monomers were joined to form organic polymers.

Stage 3: Organic polymers became enclosed in membranes to form protocells or protobionts.

Stage 4: Protobionts acquired the ability to self-replicate.
