A type of organism that feeds on other organisms is called a heterotroph.

Here's a breakdown:

* Heterotroph: An organism that cannot produce its own food and must obtain nutrients by consuming other organisms.

* Autotroph: An organism that can produce its own food through photosynthesis (like plants).

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 benefit from it, often harming the host

* Scavengers: Feed on dead organisms
