When new areas are being developed, nearby homeowners may notice an influx of displaced animals to their yards. How do these displaced animals disrupt the ecosystem of the residential yards?

The correct answer is: They compete with already present animals for sources of food.

Hope this helps!  :)

Explanation:

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.
