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.

<span>Modern humans have been around for a very short period of time. There are differences in race, asian people tend to be smaller, stuff like that. The problem is different races marry and those genes mix. If Asians only married pure blood Asians, Africans only married and procreated with other Africans thanks in hundreds of thousands of years different sub species would most likely start to occur. Seeing as how human population is all connected today, that won't happen.</span>
