Detailed explanation-1: -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-2: -Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers. Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms.

Detailed explanation-3: -Bacteria, fungi, yeast, cows, dogs, humans are all heterotrophs. They all depend on plants and other animals for their food.

Detailed explanation-4: -Heterotrophs cannot synthesise their own food and rely on other organisms both plants and animals for nutrition. A heterotroph is an organism that cannot fix carbon and uses organic carbon for growth.

Detailed explanation-5: -The three types of heterotrophs are herbivores, omnivores and carnivores, and detritivores. Heterotrophs occupy the second and third levels of food chains, feeding on autotrophs (second level) or feeding on autotrophs and other heterotrophs (third level).
