Chapter 56, Problem 15TYK
Which of the following statements reflects a concern about the effects of global climate change on tree species?
- a. The increased ozone levels may damage leaf cells, reducing photosynthetic rates.
- b. Warmer temperatures may speed tree growth, producing trees that are too tall and spindly.
- c. The combination of acid precipitation and worsening droughts may threaten many tree species.
- d. Trees may not be able to disperse fast enough to reach new habitats that meet their climatic requirements.

1. Forests can affect their local areas favorably in all of the following ways except:
A. causing sunlight to be absorbed, warming the canopy (by the green leaves of trees)
B. causing wind velocity to decrease (by the "surface roughness" of trees)
C. causing CO, to be removed from the air (by oxygenic photosynthesis in trees)
D. causing increased soil erosion (by tree roots releasing water into soils)
E. causing O2 to be released into the air (by oxygenic photosynthesis in trees)
