|
Dead, organic matter is broken down and carbon dioxide is released in tothe air
|
|
|
Carbon is leaked into the atmosphere when fossil fuels are burned
|
|
|
Volcanoes and fires vent large amounts of carbon dioxide into the sky

|
|
Decaying organisms are essential for carbon to be released back into the food web.

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: -In the carbon cycle, decomposers break down dead material from plants and other organisms and release carbon dioxide into the atmosphere, where it’s available to plants for photosynthesis.
Detailed explanation-3: -Decomposers, like fungi and bacteria, complete the food chain. Decomposers turn organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil. They complete the cycle of life, returning nutrients to the soil or oceans for use by autotrophs.
Detailed explanation-4: -Decaying leaves are nature’s compost: they help to form organic matter in the soil, and they provide nutrients to plants and decomposers (such as invertebrates, bacteria and fungi) on land and in water (Webster, 2007).
Detailed explanation-5: -Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren’t in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
