GENERAL KNOWLEDGE

Detailed explanation-1: -Fungi are heterotrophs. They can be saprophytic, parasitic or symbiotic.

Detailed explanation-2: -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-3: -All fungi constitute this group of organisms that live on sources of food and digest and absorb nutrients from them. Thus, the correct option is D. i.e. Heterotrophs.

Detailed explanation-4: -Fungi are either saprophytic (they feed on dead plant and animal material), parasitic (they feed off a living host) or symbiotic (they share a mutually beneficial relationship with another organism). Saprophytic fungi release enzymes to soften the dead plant or animal.
