Detailed explanation-1: -Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.

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: -Heterotrophs depend directly or indirectly on autotrophs for their food. They do not have photosynthetic organelles as autotrophs. So, they can not synthesise 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.
