Describe and diagram the carbon cycle. Include the terms photosynthesis; plant and animal ...

Answer to q. 1

Photosynthesis provides a source of oxygen to the atmosphere. This oxygen is used for all
plant and animal respiration. The output of respiration is atmospheric carbon dioxide, which
is, in turn, taken up by plants for the process of photosynthesis.
Decomposition is accomplished by bacteria and other organisms such as saprophytes. This
process yields atmospheric carbon dioxide.
Human combustion activities that burn fossil fuels have produced an overabundance of
carbon dioxide, which is causing climate change.

Answer to q. 2

Concepts to Consider: Starting with a cloud, the water condenses and ultimately falls to
Earth either as precipitation over land or the ocean; water percolates through the soil and may
reach the groundwater, be taken up by plants, or run off into bodies of water; water taken up
by plants may be transpired and reenter the atmosphere in this way. Water also reenters the
atmosphere via evaporation from bodies of water.
