MUSCLE PHYSIOLOGY

Detailed explanation-1: -All animals, protozoans, fungi, and most bacteria are heterotrophs. Every organism requires carbon supply in the form of fats, carbohydrates and proteins which is essential for the energy. A heterotroph obtains its carbon supply from organic materials, usually plant or animal matter.

Detailed explanation-2: -Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.

Detailed explanation-3: -Heterotrophs cannot synthesize their own food and rely on other organisms-both plants and animals-for nutrition. Technically, the definition is that autotrophs obtain carbon from inorganic sources like carbon dioxide (CO2) while heterotrophs get their reduced carbon from other organisms.
