A.
Let's break it down:
-If the study has been conducted by multiple others and they get different results, it might be a sign that something went wrong in the experiment, and the data is unreliable. For example, if everybody else timed an event and got the same exact time except for the fact that you got a different time, you may start to suspect that you had done something wrong and the data was unusable.

Answer:A
Explanation:it makes sense
It will result in growth overshoot of bear and the population will exceeds the habitat's carrying capacity.
The fishes serves as food for bears in the food chain of the ecosystem (river). The abundance of fish means there is more and enough food for bears, which in turns enhance their growth and reproduction (exponential phase).
However, bears population will continue to increase (overpopulation) and the carrying capacity (i.e., the amount of resources an habitat can provide for its inhabitants) is depleted. Thus, competition, predation, disease outbreak and others, would set in, resulting to loss of species and habitat in the long run.
