Question

Name 2 problems that can occur in a fresh water biome that can have a negative impact on Pacific NW Salmon. Describe how each of those problems could impact the salmon.

Answer 1

building of dams- fish are barricaded when they try to travel in order to reproduce. No reproduction obviously leads to the extinction of the species.

factory fumes- pollute the freshwater.

Global warming- Higher temperatures are causing the water to be evaporated more quickly because of this plants in or around the source of water are dying and animals are losing their food sources.
