* Heterotrophic means that organisms cannot produce their own food. They rely on consuming other organisms for energy and nutrients.

* Humans, like all animals, obtain their energy and nutrients by consuming plants and other animals.

* We break down the complex molecules in food into simpler ones that our bodies can absorb and use.

Other types of nutrition include:

* Autotrophic: Organisms like plants can produce their own food through photosynthesis.

* Mixotrophic: Organisms that can use both autotrophic and heterotrophic methods.

So, in short, humans are heterotrophic, meaning we need to eat other organisms to survive.
