NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Fungi have several mutualistic relationships with other organisms. In mutualism, both organisms benefit from the relationship. Two common mutualistic relationships involving fungi are mycorrhiza and lichen.

Detailed explanation-3: -All fungi are heterotrophic, which means that they get the energy they need to live from other organisms.

Detailed explanation-4: -Fungal symbionts express a variety of symbiotic lifestyles including mutualism, commensalism and parasitism (Lewis, 1985).
