DENDROLOGY

Detailed explanation-1: -They lack chlorophyll pigment because of which they cannot produce food on their own, therefore they depend on other organisms for deriving nutrition. Hence, we can say that all fungi are heterotrophic in nature.

Detailed explanation-2: -Fungi are heterotrophic. Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. They accomplish this by growing through and within the substrate on which they are feeding.

Detailed explanation-3: -Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy.

Detailed explanation-4: -A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter. Detritivores play an important role in maintaining a healthy ecosystem by recycling waste. Examples of detritivores include fungi, worms, and insects.
