Detailed explanation-1: -In contrast to autotrophs, heterotrophs are unable to produce organic substances from inorganic ones. They must rely on an organic source of carbon that has originated as part of another living organism. Heterotrophs depend either directly or indirectly on autotrophs for nutrients and food energy.

Detailed explanation-2: -Animals, like all heterotrophs, use organic materials as their sole source of carbon.

Detailed explanation-3: -A heterotroph obtains its carbon supply from organic materials, usually plant or animal matter.

Detailed explanation-4: -These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter.

Detailed explanation-5: -True: All heterotrophs have a basic process of nutrition similar. They break down the glucose formed by the autotrophs and get the energy out of nutrients by the process of respiration.
