Question

based on the results of the fishway efficiency table, which statement identifies a possible negative consequence of the fishways? hide all a the fish might become too dependent on fishways and lose their ability to migrate naturally. b the efficiency of the fishways prevents the fish population upstream from growing significantly. c the dam will not be able to produce electricity as efficiently once a fishway is added. d fish that do not normally migrate will be transported by the fishways to areas they do not typically inhabit.

Explanation:

To determine the negative consequence of fishways, we analyze each option:

• Option A: Over - dependence on fishways could lead to loss of natural migration ability, a plausible negative impact on fish behavior.
• Option B: Fishway efficiency should help, not prevent, upstream population growth (illogical).
• Option C: Fishways and dam electricity production are unrelated (no basis).
• Option D: Fishways are for migratory fish; non - migratory fish wouldn’t be transported (unlikely).

Answer:

A. The fish might become too dependent on fishways and lose their ability to migrate naturally.
