HELP ME, I HAVE TO DO THIS LIKE RIGHT AWAY CAUSE IT WAS DUE 3 DAYS AGO. Part A: Define the Problem
Despite the availability of cleaner energy sources, most of the energy used to power American
homes comes from the burning of fossil fuels such as coal and oil. The burning of fossil fuels
releases carbon dioxide into the air. Carbon dioxide is a greenhouse gas that contributes to
climate change.
Why do you think it's a challenge to reduce fossil fuel usage in homes in the United States? How
could the use of fossil fuels affect the biodiversity in neighborhoods and the surrounding
ecosystems?

from my research i have to the conclusion that 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.    

what? are the statements?
