Downhill Flow of Water
Use the figure above to answer the following question(s).
What zone is indicated by the letter "B" and what characteristics does this zone have?
What will be an ideal response?
In the transition zone, headwater streams merge to form wider, deeper, and warmer streams that flow down gentler slopes with fewer obstacles. They can be more turbid (containing suspended sediments) and slower flowing than headwater streams, and they tend to have less dissolved oxygen. The warmer water and other conditions in this zone support more producers, as well as cool-water and warm-water fish species (such as black bass) with slightly lower oxygen requirements.
