How do decomposers help the carbon cycle?
Carbon is leaked into the atmosphere when fossil fuels are burned.
Dead, organic matter is broken down and release carbon dioxide into the air
Volcanoes and fires release large amounts of carbon dioxide.
Decaying organisms are needed for carbon to be released
