High population density can cause increases in competition for resources, such as food and shelter. The table shows the number o

<h3>Answer: Region C</h3>

=============================================================

Explanation:

Check out the screenshot below.

I formed a fourth column where we divide each population over its corresponding area. For example, region A will have a population density of roughly 1312/212 = 6.19 which means there are 6.19 zebras per square km.

The higher the population density, the more competition for resources. We see that region C has the highest density at about 26.24 zebras per square km. There are more zebras competing for food/water/shelter/etc in the same relative area compared to the other regions.

What is 0.3111111111111111 as a fraction?

Citrus2011 [14]

$\sf~N=0.3\overline{1}$

There is only one repeating number, so we multiply both sides by $\sf10^1$ or $\sf10$ .

$\sf10N=3.\overline{1}$

Now subtract the original number we had to both sides, which is the same as $\sf~1N$ or $\sf~N$

So we have:

$\sf9N=2.8$

Divide 9 to both sides:

$\sf~N=\dfrac{2.8}{9}$

Multiply the fraction by 10 to get rid of the decimal in the numerator.

$\sf~N=\dfrac{28}{90}$

Simplify the fraction by dividing the numerator and denominator by 2:

$\sf~N=\boxed{\sf\dfrac{14}{45}}$
