Answer:
Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive.
These factors are essential for the growth and life span of the population of species in an ecosystem. The larger the space, the more light it obtains, and the more food the area produces; the larger the population of species in an ecosystem. having less space, light, and food, the results would be vice versa.
Deep water currents affect the number of organisms found in the area by circulating nutrients due to upwelling. Upwelling is a process where cold water surfaces and encourages nutrients to the surface. When exposed to sunlight, they initiate energy which keeps the flow of the ecosystem.
