Introduction to the Carbon Cycle
This tutorial introduces the carbon cycle
More precisely, this ratio is 100 to 50; these are the currentbest estimates for the total amount of carbon, in gigatons, used andreleased in photosynthesis and respiration each year on a globalbasis.

And yet if we don't make some attempt to describe thisprocess in the form of a global model, our understanding of thedynamics of the global carbon cycle will languish in the earlystages.
This lab works great when teaching about the carbon cycle as well
These processes form a carbon cycle in which the proportion of carbon dioxide in the atmosphere remains about the same. The animation should help you to understand how the cycle works. Note that you do not need to know about decomposition and fossilisation.
Carbon Cycle Lab- Photosynthesis and Respiration
The rising human population is adding to atmospheric carbon dioxide in other ways, too. When land is cleared for timber and farms, there are fewer trees to remove carbon dioxide from the atmosphere by photosynthesis. If the fallen trees are burned or left to rot, additional carbon dioxide is released into the atmosphere. This is particularly important when forests are cleared to make way for farms. Not only are there then fewer trees to absorb carbon dioxide, but the burning of the trees releases carbon dioxide.
