What organisms are called heterotrophic? give examples.

Heterotrophs are different organisms, from unicellular to multicellular, united by their way of feeding. These individuals, as food, use already existing organic substances, and are not able to synthesize them on their own. Examples of unicellular organisms are some bacteria and algae, all fungi, representatives of the animal kingdom, from unicellular organisms (amoeba, bodo, trypanosomes, lamblia, etc.) to animals (crocodile, wolf, lion) and humans. This also includes some plants (Venus flytrap, broomrape, rafflesia, dodder, Peter’s cross, etc.).
