Question

Role of Saprophytes in Ecosystem 300 words​

Answer 1

Answer:

Saprophytes are the living organisms that live and feed on dead and decaying organisms. They are considered extremely important in soil biology. They break down the complex organic matter into simpler substances that are taken up by the plants for various metabolic activities. Thus, saprophytes play a significant role in the ecosystem. Fungi and a few bacteria are saprophytes.

Saprophytes have certain characteristic features:

They produce filaments.

They are devoid of leaves, roots and stem.

They cannot perform photosynthesis and are heterotrophs.

They can produce spores.

The saprophytes secrete digestive juices and breakdown the organic matter around them. The fungi grow tubular structures known as hyphae that branch into the dead matter and produce digestive enzymes.

Saprophytes undergo extracellular digestion to digest the dead and decaying matter. They secrete digestive substances into the surrounding environment and break down the organic matter into simpler substances. The nutrients thus produced are absorbed directly through the cell membranes of the organisms.

In saprophytic nutrition, the proteins are digested into amino acids, starch is broken down into simple sugars, and fats are broken down into glycerol and fatty acids. These end products are transported through the cell membranes.

Answer 2

• The saprophytes are the organisms which feed on the dead and the decaying matter in the ecosystem. These organisms along with the microbes help in the decomposition of the dead plants and the animals. This decomposition is necessary as it is one of the paths for the recycling of the nutrients.
