Question

question 2
according to the graph above, what would you expect to happen to the rate of photosynthesis with growing levels of carbon dioxide in the atmosphere?
select the best response from the options, below:
a a higher carbon dioxide concentration causes a steep increase in the rate of photosynthesis - then it suddenly drops.
b a higher carbon dioxide concentration causes a steady and continuous increase in the rate of photosynthesis.
c carbon dioxide concentration increases the rate of photosynthesis to a point, then remains constant.
d carbon dioxide concentration is not a factor in the rate of photosynthesis.

Explanation:

The graph shows that as carbon - dioxide concentration increases, the rate of photosynthesis rises initially and then levels off. This indicates that carbon dioxide concentration increases the rate of photosynthesis to a point, after which it remains constant.

Answer:

C. Carbon dioxide concentration increases the rate of photosynthesis to a point, then remains constant
