The Great Lakes region is a major source of fresh water and home to a diverse group of plants and animals. Which of these factors could disturb the stability of the ecosystem?

D) The disappearance of a keystone species due to an increase in water temperature.

Explanation:

A) A decrease in fishing throughout the Great Lakes region. B) A slowdown of clear cutting and construction in the area. C) Normal snowfall in winter, ensuring that water levels remain normal. D) The disappearance of a keystone species due to an increase in water temperature.

The answer would be the disappearance of a keystone species due to an increase in water temperature.

When an ecosystem is said to be stable, it means that the communities of organisms in that ecosystem are relatively undisturbed/unchanged.

The stability of an ecosystem depends largely on the different communities of plant and animal species in interacting with the non-living components of the environment. Hence, when keystone species disappear due to increase in the temperature of the water, the various biological processes are disrupted and the stability of the ecosystem becomes threatened.

Decrease in fishing, slowdown of clear cutting and construction in the area and normal snowfall that ensures normal water levels all serve to promote the stability of the ecosystem.

The correct option is D.

i think that c)gold was found there

but i am not sure

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
