Question

beach erosion
coastal maine has beaches that are protected by dunes that have grasses growing on them. the graph shows the amount of erosion that was observed on these beaches during a six - month time period. increased storms have led to the erosion of the dunes which has caused a decrease in rooted plants on them. the loss of vegetation has led to even more beach erosion. this is considered which type of interaction?
positive feedback loop
inhibitory feedback reaction
negative feedback loop
equilibrium

Explanation:

In a positive - feedback loop, a change in a system leads to further changes in the same direction. Here, increased storms erode dunes, which reduces rooted plants, and this in turn leads to more beach erosion, continuing the cycle of increased erosion. In a negative - feedback loop, a change would lead to a counter - change to restore equilibrium. An inhibitory feedback reaction is not a standard term in this context, and equilibrium implies a stable state which is not the case here.

Answer:

positive feedback loop
