Step-by-step explanation:
Based upon the nutrition mode, the living organisms are classified as autotrophs and heterotrophs. The organism which has the ability to prepare its own food are called heterotrophs, whereas the organism which is dependent on autotrophs and other animals are called as heterotrophs.
Basically plant are called as autotrophs as they prepare their own food with help of sunlight, and water due to the presence of chlorophyll by process called photosynthesis.
Animals and human beings are called as heterotrophs as they don't have ability to prepare their own food and in turn is dependent on plant and other animals.
