Question

red in μmol photons·m⁻²·s⁻¹). the graph shows her results. t of light intensity on oxygen production based on the graph, which of the following conclusions is best supported? a) as light intensity increases, the amount of oxygen produced increases without limit. b) there is no relationship between light intensity and oxygen production. c) oxygen production increases up to a certain light intensity, after which further increase in light has little effect. d) oxygen production decreases at higher light intensities due to light damage

Explanation:

Examine the shape of the graph. Initially, as light - intensity increases, oxygen production rises. But as light - intensity reaches a certain value, the curve flattens out, indicating that further increases in light intensity have little impact on oxygen production.

Answer:

C) Oxygen production increases up to a certain light intensity, after which further increase in light has little effect.
