Here's why:

* Autotrophs are organisms that can produce their own food through processes like photosynthesis (using sunlight) or chemosynthesis (using chemical energy).

* Heterotrophs rely on consuming other organisms (plants, animals, or decaying matter) to obtain the energy and nutrients they need to survive.

Examples of heterotrophs include:

* Animals: Lions, birds, fish, insects

* Fungi: Mushrooms, molds

* Bacteria: Many types of bacteria that decompose dead organisms
