Explanation:

A heterotroph is an organism which depends on plants or other animals for food because it cannot manufacture its own food. All animals are heterotrophs while green plants are autotrophs because they can manufacture their own food using chlorophyll in a process known as photosynthesis. Heterotrophs feed on complex organic food materials.
