Question 1

Which of the following best defines 'climate' as used in ecology?

Accepted Answer

The average weather conditions in a region over a long period of time.

Question 2

How does the tilt of the Earth's axis contribute to global climate patterns?

Accepted Answer

It results in unequal heating, leading to seasonal changes and varying solar radiation at different latitudes.

Question 3

Which equation best represents the relationship between solar energy input and latitude?

Accepted Answer

$$I = I_0$ \cos(	heta)$$

Question 4

Why do deserts often form on the leeward side of mountain ranges?

Accepted Answer

Moist air rises and cools on the windward side, losing moisture as precipitation, leaving dry air to descend on the leeward side.

Question 5

Which of the following is an abiotic factor in an ecosystem?

Accepted Answer

Temperature

Question 6

A major concern regarding global climate change is:

Accepted Answer

The ability of organisms to adapt quickly enough to survive changing conditions.

Question 7

Which of the following best describes a biome?

Accepted Answer

A large geographic area characterized by specific climate conditions and particular types of plants and animals.

Question 8

Which biome is characterized by high biodiversity, warm temperatures, and high rainfall year-round?

Accepted Answer

Tropical rainforest

Question 9

Which of the following is a key difference between wetlands and intertidal zones?

Accepted Answer

Wetlands are saturated with water either permanently or seasonally, while intertidal zones are periodically submerged and exposed due to tides.

Question 10

Which aquatic zone is most likely to support photosynthetic organisms?

Accepted Answer

Photic zone

Question 11

Biogeography is best defined as:

Accepted Answer

The study of the geographic distribution of species and ecosystems.

Question 12

Which of the following best explains why ocean currents are important for global climate?

Accepted Answer

They distribute heat from the equator toward the poles, moderating climate.

Question 13

A scientist observes that a certain fish species is only found in the photic zone of a lake. Which abiotic factor most likely limits its distribution?

Accepted Answer

Availability of sunlight

Question 14

Which of the following is an example of dispersal in biogeography?

Accepted Answer

A bird species colonizing a new island after being blown off course.

Question 15

Which of the following scenarios best illustrates the effect of an abiotic factor on a population?

Accepted Answer

A drought causes a decline in plant growth, reducing food for herbivores.

Question 16

If the average annual temperature in a region increases by $$2^\circ C$$, which biome is most likely to expand into neighboring areas?

Accepted Answer

Desert

Question 17

Which of the following best describes the main difference between tropical forests and deserts?

Accepted Answer

Tropical forests have high rainfall and dense vegetation, while deserts have low rainfall and sparse vegetation.

Question 18

Which of the following is a plausible consequence of rapid global climate change for terrestrial biomes?

Accepted Answer

Species may not adapt quickly enough, leading to shifts in biome boundaries and possible extinctions.

Question 19

Which of the following is NOT a characteristic used to define a biome?

Accepted Answer

Genetic variation within a single species

Question 20

A student claims that all aquatic biomes are identical because they are all made of water. Which statement best refutes this misconception?

Accepted Answer

Aquatic biomes differ in salinity, depth, and light penetration, which influence the types of organisms present.
