Question 2 • PARTA - EOP: PGCPS BIOGEOCHEM CR (FALL2026) - 798113

How could the dam affect the resources of the local watershed? Check all that apply.

Answer
A
Fish would not be able to migrate up the river to reproduce.
B
Sediment carried by the flowing river would get trapped.
C
There would be more space for forest growth.
D
The number of habitats for local wildlife would increase.
E
Birds that depend on fish may go hungry.

Explanation

A dam can block fish from migrating upstream to reproduce, and it traps sediment that would otherwise travel downstream. If fewer fish are available, birds that depend on them may go hungry. The dam would not necessarily create more space for forest growth or increase the number of wildlife habitats.
