Answer: At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis. At higher light intensities (plateau of graph), further increasing the light intensity does not increase the rate of photosynthesis meaning that another factor is limiting photosynthesis.
Do mammals live on land or water?
A majority of mammals live on land, although some are aquatic and some are aerial, and a few are “fossorial” (live underground).
