hunting and killing prey for food changing carbon dioxide and water into food absorbing food from dead organisms producing food from oxygen and sunlight
I gave my students this multiple choice question: How do decomposers obtain their food?

Only one answer is correct among these 4 choices:
- hunting and killing prey for food
- changing carbon dioxide and water into food
- absorbing food from dead organisms
- producing food from oxygen and sunlight

Could you tell me which one is correct?

absorbing food from dead organisms
