Decomposers Break Down Carbon Compounds in Rotating Leaves. Suggest 2 ways the Carbon in these Leaves Could Get Back Into The Air
Answers
An example of a decomposer in a forest ecosystem.
Written by Terri Schab
Decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. Elements such as carbon, nitrogen and phosphorus exist in limited amounts on Earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. It is still extremely important that other nutrients be retained by the process of re-use. Decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. Without this breakdown of dead material, dead bodies would pile up. So decomposers also play a role in clean up also. Without them, life might not continue as we know it and dead material would overwhelm the Earth.
Explanation:
Decomposers Recycle Nitrogen
Nitrogen is needed by organisms to make proteins and nucleic acid. Our atmosphere has a lot of nitrogen, but it is not in a form that can be used by organisms. Special bacteria and lightning can change the nitrogen into a form that can be used. This nitrogen can be used by plants, the foundation of the food chain. When organisms die, decomposers break down the dead bodies and the nitrogen is released and another type of bacteria breaks it down into gaseous nitrogen. Without decomposers and other types of bacteria, the nitrogen cycle would not be maintained. In all likelihood, plants would die off and the food chain would dissolve.
please tell me the answer aswell I need not know it
