What happened to North American coastal waters when the great white shark population decreased?(1 point)
As an AI language model, I don't have a factual knowledge of current events, but I can provide a response based on data from past research.
When the great white shark population decreased in North American coastal waters, it could potentially have led to a cascade of ecological effects. The great white shark is a top predator in the food chain, and their absence could have caused an increase in the population of their prey, such as seals and sea lions. This, in turn, would have led to a decrease in the population of the prey's food sources (such as fish), leading to a decrease in the productivity of the ecosystem. Additionally, with fewer great white sharks, certain fish populations such as rays and skates may have increased, causing further imbalance in the ecosystem.
