Solution

Action spectrum is a graph curve depicting the relative rates of a physiological process like photosynthesis at different wavelengths of light, whereas absorption spectrum is the graph curve depicting the amounts of different wavelengths of light absorbed by a particular substance, commonly a-pigment.
