What is a producer in a food chain?

• A consumer that feeds on plants and other producers

• An organism that only eats other organisms

• An organism that produces its own food through photosynthesis or chemosynthesis.

• A type of decomposer that breaks down dead organic matter

Name an example of a consumer in a food chain.

• Giraffe

• Lion

• Tiger

• Elephant

What is the role of a decomposer in a food chain?

• To break down dead organisms and waste, returning nutrients to the soil

• To provide structural support for the food chain

• To regulate the population of primary consumers
