4. The clarity of lake water is affected by the amount of phytoplankton (marine plants), soil, clay, and other solids suspended in the lake. Suppose the concentration of carbon dioxide in the atmosphere
changed from 340 ppm to 380 ppm from 1980 to 2005. What effect would this have on the
occurrence of the full body plate trait? Explain your answer. Hint: Think about how carbon dioxide is
related to photosynthesis. (10 points)

More photosynthesis will occur.

Explanation:

Carbon dioxide has a great relationship with photosynthesis because it is a raw material used by the plant during the process of photosynthesis. If carbondioxide gas concentration increases, more rate of photosynthesis will occur. Carbon dioxide gas enters into the plant body through small openings through stomata which react with plants produces oxygen and glucose, so more carbon dioxide means more food is produced by the plant.
