NEET BIOLOGY

Detailed explanation-1: -Bacteria, fungi, yeast, cows, dogs, humans are all heterotrophs. They all depend on plants and other animals for their food.

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 are the organisms that do not contain chlorophyll pigment like autotrophic animals. Thus, they cannot carry out the process of photosynthesis which is essential for the preparation of food.
