How would you expect the relative abundance of C3 versus C4 and CAM species to change in a geographic region whose climate becomes much hotter and drier, with no change in CO2 concentration?
MAKE CONNECTIONS Review the discussion of feedback regulation in Concept 1.1. Could effects of globalwarming on peatlands alter CO2 concentrations in waysthat result in negative or positive feedback? Explain.
Respond to the following questions.
Why might it seem surprising that green light can drive any photosynthesis, given that chlorophyll, the major photosynthetic pigment, is green?
How can it do this?
Suppose that CO2 levels were to rise to 600 ppm, which in fact probably was their level about 300 million years ago. What effect would you suppose that might have regarding competition between C3 and C4 plants? In other words, which of the two kinds of plants would the change favour and why?
