The graph shows that the rate of photosynthesis increases with increased light intensity, other conditions being constant.
<h3>Photosynthesis and light intensity</h3>
From the graph, the rate of photosynthesis increases with an increase in light intensity.
At low light intensity, the photosynthesis rate increases with an increase in the concentration of carbon dioxide and level off at some point.
With medium light intensity, the rate of photosynthesis is about twice that of low light intensity under the same concentration of carbon dioxide. It also gradually levels off when the concentration of carbon dioxide reached a particular point.
The same trend applies to high light intensity. The rate of photosynthesis increased accordingly, much more than low and medium-intensity light.
Both light and carbon dioxide concentration can limit the rate of photosynthesis. When both factors are abundant, photosynthesis can be limited by other factors such as water, nutrient, etc.

Answer:
C
Explanation:
A rainforest is humid, therefore, water uptake would likely not be an issue. However, rainforests have a huge number of trees, often these are very tall. These large trees might block out the sun from the smaller plants nearer the ground. This means they would struggle to properly photosynthesise, as they wouldn't have the necessary light energy.
Therefore, as a survival adaptation, it is likely that an allele that produced broader leaves for photosynthesis would be selected for in this population. Broader leaves would give a larger surface area for the plant to absorb light energy to perform photosynthesis.
