What is a food chain?

• A series of organisms that produce their own food

• A series of plants that grow in a specific order

• A series of animals that live in the same habitat

• A series of organisms that are dependent on each other for food

• Carnivores

• Consumers

• Producers

What role do decomposers play in a food chain?

• They break down dead organisms and recycle nutrients

• They provide energy for producers

• They produce their own food

• They eat primary consumers

What happens when multiple food chains are combined?

• A trophic level is formed

• An energy cycle is formed
