What feed on other organisms or dead organic matter meaning they are?

Organisms that feed on other organisms or dead organic matter are known as heterotrophs. They rely on consuming organic material for energy and nutrients, as they cannot produce their own food like autotrophs do through photosynthesis. Heterotrophs include a wide range of life forms, such as animals, fungi, and some bacteria, playing crucial roles in ecosystems as decomposers, predators, and scavengers.
