What role do producers play in an ecosystem?

• Producers create their own food through photosynthesis and provide energy for consumers.

• Producers consume other organisms for energy.

• Producers decompose organic matter and recycle nutrients.

• Producers are organisms that rely on consumers for energy.

How do food chains and food webs show energy flow?

• Both illustrate how energy is transferred from producers to consumers, but food webs show multiple pathways.

• Food chains show energy flow, while food webs do not.

• Food webs are simpler than food chains in showing energy flow.

• Food chains only include producers, while food webs include only consumers.

• A food chain is a complex network, while a food web is a simple linear sequence.

• A food chain includes only plants, while a food web includes both plants and animals.

What is a decomposer?
