A consumer is:

• an organism that produces its own food

• a nonliving component of the ecosystem

• an organism that consumes other organisms for energy

• a type of plant that uses sunlight for food

The difference between a producer and consumer is:

• Producers make their own food, while consumers eat other organisms.

• Producers eat other organisms, while consumers make their own food.

• Both producers and consumers make their own food.

• Neither producers nor consumers need food.
