Any omnivore, humans for example.
Heterotrophs are organisms that cannot make their own food. They have to depend on other plants and animals for nutrition.
Autotrophy is the ability of an organism to produce its own food using inorganic compounds, such as plants that photosynthesize. Heterotrophy is when an organism cannot produce its own food and must obtain nutrients by consuming other organisms, like animals that consume plants or other animals.
Consumers are organisms that cannot make their own food.
saprobes
Animals that cannot make their own food and must eat other animals or plants to obtain energy are known as heterotrophs. These organisms are a part of food chains, where each member feeds on the organism below it in the chain to acquire energy.
A heterotroph is an organism that cannot produce its own food. Humans, as well as all other animals are consumers, because they have to eat other animals or plants for energy. Fungi and bacteria are also heterotroph, because they feed on decomposing matter (they use this matter as food to produce energy).
Animals and plants are very different than fungus. Animals cannot produce their own food. Plants can produce their own food.
Plants make food where animals eat it
Plants (or at least most plants; there are some exceptions) do not eat any other organism; they create their own food out of water, air, minerals and sunlight. Whereas, all animals have to eat some other organism to survive. Some eat plants and some eat other animals, but every animal eats some kind of organism. So plants produce the food upon which all animals ultimately depend (because even if an animal eats other animals, the animals that it eats depend upon plants).
yes.....solar energy is important to them because it helps in photosynthesis i.e.it helps in preparing of food for plants as well as animals. ANY ORGANISM IN THIS WORLD CANNOT LIVE WITHOUT FOOD and ANIMALS ARE INCLUDING HUMAN DEPENDS ON PLANTS DIRECTLY OR INDIRECTLY.SO IT IS ESSENTIAL.
They dont have chloroplasts. Plants have them.
Systems for obtaining food (that is not produced internally by the organism as happens in plants).
