Practice AP Environmental Science questions on how clearcutting changes soil, streams, forest habitats, carbon storage, and climate.
The following diagram shows how an area changed over time. The dominant vegetation in each stage is labeled in the diagram. Each roman numeral represents a stage in the ecological process.
Identify the independent variable in the experiment.
Explain why the water temperature might change because of clear-cutting trees in forest B.
After the experiment was completed, land developers constructed a golf course in the clear-cut area of forest B. To prepare the land, developers removed any remaining stumps and newly grown trees and began planting and fertilizing new grass. The researchers are interested in the effect the golf course may have on the water quality of the river. To monitor the river in forest B, the researchers repeated the experiment once the golf course had been constructed.
