what are the four processes of the carbon cycle |
photosynthesis respiration decomposition combustion |
|
|
what happens to carbon in photosynthesis |
carbon in the form of co2 from air and water is absorbed by plants when they carry out photosynthesis - it becomes carbon compounds in plant tissue. |
|
|
what happens to carbon after it is absorbed by plants |
the carbon is then passed onto the primary consumers when they consume the plants and then passed onto other secondary and tertiary consumers when they eat the plants |
|
|
what happens to the carbon after it is consumed by the tertiary consumers |
when the animals die the carbon is digested by microorganisms called decomposers = saprobiontic nutrition |
|
|
how is carbon returned to the atmosphere |
carbon is returned to the atmosphere when organisms respire including decomposers |
|
|
describe the daily changes in co2 concentrations in the atmosphere |
co2 concentrations fall throughout the day because its being taken in by plants - co2 concentrations increase at night because its no longer being taken in by photosynthesis but all organisms are still respiring |
