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: –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-3: -Heterotrophs are the organism that are not able to synthesize their own food. Thus they are dependent on other organisms for food. Animals depend on plants or other animals for food. Hence they are heterotrophs.

Detailed explanation-4: -All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic. In contrast, green plants, red algae, brown algae, and cyanobacteria are all autotrophs, which use photosynthesis to produce their own food from sunlight.

Detailed explanation-5: -Answer and Explanation: There are no animals that could be considered autotrophic. Examples of organisms that are autotrophic are plants and algae, and they have specialized cell organelles that have the ability to power the process of photosynthesis.
