Carnivors: such as lions, tigers and bears
All animals who eat 1st order heterotrophs.
Virtually all animals are heterotrophs (i.e. animals that eat things for nourishment).
Heterotrophs are living things that have to eat other living things to survive. That would be an animal, since plants make their own food.Heterotrophs that eat other heterotrophs would be animals that eat other animals. Heterotrophs that eat only other heterotrophs would be a carnivore. If the heterotroph eats both heterotrophs (animals) and autotrophs (plants), that would describe an omnivore.
Heterotrophs that eat both plant and animals are referred to as omnivores. Animals that only eat plants and herbivores and those who only eat meat are carnivores.
Carnivores
Heterotrophs are organisms that feed on other life forms. Animals are heterotrophs. Animals that eat other animals are carnivores.
omnivore
Echinoderms, like all animals, are heterotrophs and need to eat food to survive.
Heterotrophs can eat autotrophs or other heterotrophs.
A heterotroph cannot produce its own food and must therefore consume other organisms to live. All animals and fungi are heterotrophs.
Heterotrophs rely on autotrophs or other heterotrophs for energy. Autotrophs, such as plants, can make their own food using photosynthesis. Heterotrophs, such as animals, must eat plants or other animals to obtain their energy.
An Omnivore eats plants (autotrophs) and other animals (heterotrophs). Example of Omnivores are humans.
