Motor neurons are involved in the skeletal muscle contractions in vertebrates, as the process is a synaptic one. These occur due to a conscious effort by the brain, from which these signals originate. In some reflexes, the signal originates from the spinal cord.
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.
