NEET BIOLOGY

Detailed explanation-1: -Heterotrophic organisms depend on other organisms for deriving nutrition. Example: Fungi, animals, etc. Animals are heterotrophs. They do not possess chlorophyll pigment to undergo photosynthesis, hence they feed on living organisms.

Detailed explanation-2: -Heterotrophs are the consumers of the ecosystem; they cannot make their own food. They use, rearrange, and ultimately decompose the complex organic materials built up by the autotrophs. All animals and fungi are heterotrophs, as are most bacteria and many other microorganisms.

Detailed explanation-3: –Option B is correct because all animals and fungi are heterotrophs as they can’t produce their own food. They all depend on the autotrophs( primary producers) and on other organisms for food.

Detailed explanation-4: -Heterotrophs are a group of organisms that obtain their energy by consuming other organisms. They are also called consumers or ‘other feeders. ‘ All the animal and fungi species in the world are heterotrophs, and so are many protists and bacteria. There are also a few plant species that trap insects for nutrition.
