NEET BIOLOGY

Detailed explanation-1: -Heterotrophs do not synthesize their own food and organisms that feed on dead organic matter are called saprophytes. Saprophytic fungi feed on dead remains and are extreme help to us in our garden as they break down organic matter into minerals and nutrients.

Detailed explanation-2: -All fungi are heterotrophic, which means that they get the energy they need to live from other organisms. Like animals, fungi extract the energy stored in the bonds of organic compounds such as sugar and protein from living or dead organisms. Many of these compounds can also be recycled for further use.

Detailed explanation-3: -What are saprophytic fungi? Saprophytic fungi feed on dead plant and animal remains. Many are extremely beneficial, breaking down this organic material into humus, minerals and nutrients that can be utilised by plants. Without these fungi we would also disappear under a mountain of unrotted dead leaves and logs!

Detailed explanation-4: -Decomposers. Figure 24.5. 4: Fungi growing on a dead tree secrete enzymes that can break down even tough wood fibers that no other organisms can digest. Decomposers are heterotrophs that break down and feed on the remains of dead organisms and other organic wastes such as feces.

Detailed explanation-5: -Saprophytes are organisms that can’t make their own food. In order to survive, they feed on dead and decaying matter. Fungi and a few species of bacteria are saprophytes.
