What is a heterotroph?
Where does an heterotroph get its energy for food?
Give an example of both of autotroph and heterotroph.

Autotrophs are an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

Most autotrophs make their "food" through photosynthesis using the energy of the sun.

Hetrotrophs an organism deriving its nutritional requirements from complex organic substances.

Heterotrophs eats other plants or animals for energy and nutrients cannot make their own food, so they must eat or absorb it.

Plants, algae, and some types of bacteria are autotrophs.

Dogs, birds, fish, and humans are all examples of heterotrophs.
