Question

How are autotrophic organisms and heterotrophic organisms obtain their food?

Accepted Answer

We know that autotrophic organisms (some bacteria, all algae, and all plants) obtain water, carbon dioxide, and minerals from their environment and prepare their food which is then used for growth and energy. On the other hand, heterotrophic organisms (most bacteria, and all protozoans, fungi, and animals) obtain their food from other organisms and use it for growth and energy.
