NEET BIOLOGY

Detailed explanation-1: -“Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.” All animals and non-photosynthetic plants are classified as heterotrophs since they are unable to prepare food.

Detailed explanation-2: -They can’t make their own food like Green plants. Heterotrophic organisms have to take in all the organic substances they need to survive. All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic.

Detailed explanation-3: -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-4: –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-5: -This mode of nutrition in animals is known as heterotrophic. Example: Fungi, humans, and other animals are directly or indirectly dependent on the plants for food and nutrition requirements. Hence the mode of nutrition in animals is known as heterotrophic Nutrition.
