Q: Which equation best represents the relationship between climate and the distribution of organisms?

$$\text{Climate} = \text{Temperature} + \text{Precipitation}$$

Q: Which equation would you use to calculate population density?

$$\text{Population Density} = \frac{\text{Number of Individuals}}{\text{Area}}$$

Accepted Answer

Landscape ecology

Question 8

Which of the following is an example of a microclimate?

Accepted Answer

The climate inside a shaded crevice under a rock

Question 9

If a mountain range is located near an ocean, which side of the mountain is likely to be drier, and why?

Accepted Answer

Leeward side, due to descending dry air absorbing moisture

Question 10

Which biome is characterized by high mean annual temperature and high mean annual precipitation, according to the graph provided?

Accepted Answer

Tropical forest

Question 14

Which of the following best explains why the tropics receive more heat and light than other regions?

Accepted Answer

The sun is overhead at the equator, resulting in direct sunlight

Question 15
