EVERYDAY SCIENCE

Detailed explanation-1: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

Detailed explanation-2: -Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting.

Detailed explanation-3: -Decomposers act on the dead matter, e.g. by secreting the enzymes and digesting the matter externally. Saprotrophs contribute to the decomposition process by extracellular digestion, i.e., they digest dead matter externally by secreting enzymes and then absorbing the nutrients.

Detailed explanation-4: -Explanation: Decomposers play a vital role in keeping the food chain functioning properly. As decomposers break down the remains of dead organisms and produce waste, nutrients are recycled back into the soil for producers (plants) to absorb through their roots.

Detailed explanation-5: -When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.
