Question

multiple choice question
how is the output of photosynthesis related to the amount of light available at different light intensities?
linear increase at low light intensities and saturation at high light intensities
saturation at low light intensities and linear increase at high light intensities
linear decrease at low light intensities and saturation at high light intensities
linear increase at both low and high light intensities

Explanation:

At low light intensities, the rate of photosynthesis is limited by the amount of light available, so there is a linear increase in the output of photosynthesis as light intensity increases. At high light intensities, other factors such as the availability of carbon - dioxide or the capacity of the photosynthetic apparatus become limiting, leading to saturation of the photosynthesis rate.

Answer:

A. Linear Increase at low light intensities and saturation at high light intensities
