The Carbon Cycle with emphasis on the role of decomposers, saprophytes in Nutrient Cycling. Major carbon sources and sinks.
Carbon is required by all organisms. ... The Carbon Cycle is the circulation of carbon in various forms through nature. The source of the carbon found in living matter is carbon dioxide (CO2) in the air or dissolved in water. Carbon dioxide dissolves readily in water. ... The carbon in limestone or other sediments can only be released to the atmosphere when they are subducted and brought to volcanoes, or when they are pushed to the surface and slowly weathered away. On land and in water, plants (producers) take up carbon dioxide and convert it into carbohydrates, through photosynthesis. This carbon in the plants now has 3 possible fates:
1. It can be liberated to the atmosphere by the plant through respiration as carbon dioxide.
