Differences between autotrophic and heterotrophic organisms.

Autotrophs and heterotrophs are organisms that are characterized depending on the nature of their diet. There is also another type of organisms called saprophytes.

Autotrophs are organisms that create their food through a process called photosynthesis, using water, carbon dioxide in the presence of sunlight and chlorophyll. An example is green plants.

Heterotrophs are organisms that get food from other plants and animals. They cannot create their own food and depend on other living organisms for food. An example is all animals, birds.
