Answer:
o The beavers will not have a suitable habitat available and will gradually decline in number.
Step-by-step explanation:
According to this question, an earthquake that occurs near a river system weakens a dam wall built by beavers, which are aquatic rodents, and causes the dam to collapse. This initial earthquake will damage the habitat of these aquatic animals (beavers), which is barricaded by the walls built by them around the dam over time.
The walls prevent the constant flow of water but when the walls of the dam collapses, the water in the dam begins to flow excessively i.e floods. This causes the loss of habitat of beavers, hence, resulting in the declination of number
