Organisms that consume primary producers
B
Organisms that compete with primary consumers for resources
C
Organisms that break down dead organic material and recycle nutrients
D
Organisms that produce their own food through photosynthesis
Verified step by step guidance1
Understand the role of decomposers in an ecosystem. Decomposers are organisms that break down dead organic material, such as dead plants and animals, and recycle nutrients back into the ecosystem.
Recognize that decomposers are different from primary producers, which are organisms that produce their own food through photosynthesis, such as plants and algae.
Identify that decomposers do not consume primary producers directly; instead, they break down the remains of dead organisms, including primary producers, to release nutrients.
Note that decomposers do not compete with primary consumers for resources. Primary consumers are organisms that eat primary producers, while decomposers work on dead organic matter.
Conclude that the best description of decomposers in an ecosystem is that they break down dead organic material and recycle nutrients, supporting the ecosystem's nutrient cycle.
