correct one.
Based on what you know of photosynthesis, what effect would clear cutting of large
forests and leaving the cut trees in the forest have on the amount of carbon dioxide
in the atmosphere?
A) There would be no change in carbon dioxide levels since humans put carbon
dioxide into the atmosphere by burning fossil fuels.
B) The amount of carbon dioxide would be decreased since the trees would no
longer be living.
C) The amount of carbon dioxide would be the same since the reaction rates of
photosynthesis and respiration are equal.
D) It would increase the level of carbon dioxide since less photosynthesis would be
taking place. - ANSWER D) It would increase the level of carbon dioxide since less
photosynthesis would be taking place.
