recycle energy and materials from dead organisms
|
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 or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.
Detailed explanation-3: -Decomposers break down organic material into carbon dioxide and water, as well as nutrients. Nutrients like nitrogen and phosphorous in soils are essential for producers. The CO2 released during decomposition can then be used by plants during photosynthesis.
Detailed explanation-4: -Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat.
