Explain the Carbon Cycle.

• Nature's way of circulating molecules between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

• Living organisms take in oxygen to break down food molecules to get chemical energy for cell functions.

• Nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.

• Nature's way of filtering CO2 from the atmosphere through plants which use it to create oxygen.
