In an ecosystem, what is the relationship between decomposers and consumers?
A
Decomposers consume producers directly for energy.
B
Consumers and decomposers compete for the same food resources.
C
Consumers rely on decomposers to recycle nutrients back into the ecosystem.
D

Verified step by step guidance1
Understand the role of decomposers: Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, including dead plants and animals, into simpler substances.
Recognize the role of consumers: Consumers are organisms that obtain energy by eating other organisms. They can be herbivores, carnivores, or omnivores.
Identify the relationship: Decomposers break down organic matter, releasing nutrients back into the soil and environment, which are then available for producers (like plants) to absorb.
Connect the cycle: Consumers rely on producers for their energy needs. When consumers eat producers or other consumers, they indirectly benefit from the nutrients recycled by decomposers.
Conclude the relationship: Decomposers are crucial for nutrient cycling, ensuring that essential elements are available for producers, which in turn support consumers, maintaining the balance in an ecosystem.
