Answer:
As we can see the population of the blacktip shark decreases over time and it is at the verge of extinction by 2006. This might be because the blacktip sharp is not better adapted to live in the coast of North Calorina. It might have predators in an abundant amount due to which their population declines.
The population of cownose is zero in 1970 but it gradually start increasing over the years. The population is abundant over the years because the cownose introduced into this ecosystem might be better adapted to live in the coasts of North Calorina.
The population of the bay scallops increases over the initial years and then gradually starts to decrease. This might be because a disease or a predator might have attacked the population.
