Which process do plants use to make food?

Photosynthesis, using sunlight and carbon dioxide.

Respiration during nighttime only.

Using water and energy from animals.

Eating soil nutrients directly.

1

What role do decomposers play in an ecosystem?

They only eat living plants.

They produce food for consumers.

They break down dead matter and recycle nutrients.

They create energy from sunlight.
