## Part 2
### 1. Calculate the population density of the following countries.
Population density is calculated as the population divided by the land area. Here are the computations for each country:
[tex]\[
\text{Density} = \frac{\text{Population}}{\text{Land Area}}
\][/tex]
#### Canada
[tex]\[
\text{Density} = \frac{32,805,000}{9,976,140} \approx 3.29 \, \text{people/km}^2
\][/tex]
#### China
[tex]\[
\text{Density} = \frac{1,306,313,800}{9,596,960} \approx 136.12 \, \text{people/km}^2
\][/tex]
#### Japan
[tex]\[
\text{Density} = \frac{127,417,200}{377,835} \approx 337.23 \, \text{people/km}^2
\][/tex]
#### India
[tex]\[
\text{Density} = \frac{1,080,264,400}{3,287,590} \approx 328.59 \, \text{people/km}^2
\][/tex]
#### Monaco
[tex]\[
\text{Density} = \frac{32,410}{2} = 16,205 \, \text{people/km}^2
\][/tex]
#### Spain
[tex]\[
\text{Density} = \frac{40,341,500}{504,782} \approx 79.92 \, \text{people/km}^2
\][/tex]
#### United Kingdom
[tex]\[
\text{Density} = \frac{60,441,500}{244,820} \approx 246.88 \, \text{people/km}^2
\][/tex]
#### United States
[tex]\[
\text{Density} = \frac{295,734,100}{9,629,091} \approx 30.71 \, \text{people/km}^2
\][/tex]
Here is the updated table of densities:
| Country | Population | Land Area ([tex]$km^2$[/tex]) | Density ([tex]$people/km^2$[/tex]) |
|-----------------|------------------|--------------------|-------------------------|
| Canada | 32,805,000 | 9,976,140 | 3.29 |
| China | 1,306,313,800 | 9,596,960 | 136.12 |
| Japan | 127,417,200 | 377,835 | 337.23 |
| India | 1,080,264,400 | 3,287,590 | 328.59 |
| Monaco | 32,410 | 2 | 16,205 |
| Spain | 40,341,500 | 504,782 | 79.92 |
| United Kingdom | 60,441,500 | 244,820 | 246.88 |
| United States | 295,734,100 | 9,629,091 | 30.71 |
### 2. What does population density indicate?
Population density indicates the number of people living per unit of area, usually per square kilometer (km²). This metric helps to understand how crowded or sparsely populated a country or region is. Higher population density indicates more people living in a given area, which can impact resources, infrastructure, and quality of life. Conversely, lower population density suggests fewer people and potentially more open space and resources.
### 3. Dispersion Patterns
Identify the type of dispersion pattern (clumped, uniform, random):
a. A bunch of mushrooms growing on a rotting log.
Dispersion Pattern: Clumped
b. The sage plant secretes toxins, a chemical that kills off surrounding plants in a circle around the individual sage plants.
Dispersion Pattern: Uniform
c. Dandelions have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment.
Dispersion Pattern: Random
d. A herd of elephants gathers around a watering hole.
Dispersion Pattern: Clumped
