Imagine two new volcanic islands spring up in the middle of the ocean. Each island is quickly founded by a few individuals of a

species of aquatic bird that requires fresh water to thrive. The two islands differ in rainfall, one wetter and one drier. Assuming that rainfall determines carrying capacity for these birds, and that rainfall is consistent over time, what might the growth curves for the bird populations look like over many years for the two islands

Answer:

<em>The correct answer is the option on the upper right .</em>

Explanation:

Aquatic birds that require fresh water to thrive need to be around a source of fresh water. The wetter island has more fresh water than the drier island. This means that both island will be occupied from a population of zero, to an optimum stable population, which is indicated as the graph moves from zero to its maximum point, and then levels out. Th drier island will have the same pattern of curve, but will only be able to support a much smaller population, which is why the curve for the drier island is less than that of the wetter region.

lisov135 [29]

Answer:

The biotic components like plants control floods and soil erosion. The roots of the plants hold the soil and prevent soil erosion. Roots also make the soil porous and allow the infiltration of water, hence preventing floods. Dense forests slow down the water flow and keep a check on the floods and soil erosion.
