LenaWriter [7]

Heterotrophs are organisms that must consume food from other organisms because they are unable to synthesize their own food molecules.

<h3>What is heterotrophs?</h3>
  • An organism is referred to be a heterotroph if it is unable to manufacture food on its own and must obtain it from other sources of organic carbon, primarily plant or animal materials.
  • Heterotrophs are primary, secondary, and tertiary consumers in the food chain but not producers.
  • Because they eat producers or other consumers, heterotrophs are referred to as consumers.
  • Humans, dogs, and birds are all instances of heterotrophs.
  • In a food chain, a group of creatures that supply energy and nutrients to other organisms, heterotrophs occupy the second and third levels.
  • An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy.
  • Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition."
  • Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients.
