Here's why:

* Hetero means "other"

* Troph means "nourishment"

So, heterotrophs get their nourishment by consuming other organisms.

There are different types of heterotrophs, including:

* Herbivores: Eat plants

* Carnivores: Eat other animals

* Omnivores: Eat both plants and animals

* Parasites: Live in or on another organism and feed off of it

* Decomposers: Break down dead organisms and waste
