Question

Help pls i need an answer right away

One observation that scientists made was that the willow population increased as the elk were forced to forage in more varied areas to avoid
wolves. This resulted in the beaver population increasing, as they had more resources to build dams to provide shelter through the winter. What
other effect would you expect to see?
A) Beaver population will decrease, because more dams will reduce the number of willows,
OB) Ek will increase in population, since the willow population has increased.
C) Migratory fish populations will decrease, because dams prevent them from returning upstream to mate.
D) Wolves will increase in population, because elk are not eating as many willows

Answer 1

I think I would say C

Step-by-step explanation:

I say C since it couldn't be B since the beaver population increased, not decreased

I feel like it wouldn't be D either since it doesn't really make sense. Wolves weren't affected when the Elk population decreased.

I wouldn't say B either since it said that the Elk population decreased because of the willows.
