Question 1

Which level of ecological research focuses on how the structure, physiology, and behavior of an individual organism help it meet environmental challenges?

Accepted Answer

Organismal ecology

Question 2

A scientist is studying the effect of predation on the reproductive rate of flamingos in a wetland. At which level of ecological research is this study conducted?

Accepted Answer

Population ecology

Question 3

Which of the following best describes the main focus of ecosystem ecology?

Accepted Answer

The flow of energy and cycling of chemicals between organisms and their environment

Question 4

Which physical factor has the strongest effect on the distribution of terrestrial organisms?

Accepted Answer

Climate (temperature and precipitation)

Question 5

Why do deserts often form on the leeward side of mountains?

Accepted Answer

Cool, dry air absorbs moisture as it descends, creating a rain shadow

Question 6

Which of the following is a major abiotic factor that defines aquatic biomes?

Accepted Answer

Light penetration

Question 7

What is the main difference between weather and climate?

Accepted Answer

Weather is short-term variation, climate is long-term patterns

Question 8

Which equation best represents the relationship between temperature change and elevation in mountains?

Accepted Answer

$$\Delta T = -6^\circ C \text{ per } 1000 \text{ m increase in elevation}$$

Question 9

A region experiences high precipitation near the equator and arid conditions near 30° latitude. What is the primary cause of this pattern?

Accepted Answer

Descending dry air absorbs moisture at 30° latitude

Question 10

Which of the following is a likely consequence of rapid climate change?

Accepted Answer

Decreased biodiversity and altered food supplies

Question 11

Which biome is characterized by high annual precipitation and a dense canopy layer?

Accepted Answer

Tropical forest

Question 12

Which of the following best explains why ocean currents can moderate the climate of nearby land?

Accepted Answer

Water has a high specific heat, absorbing and releasing heat slowly

Question 13

Which of the following is an example of a biotic factor influencing microclimate?

Accepted Answer

Shade cast by a tree altering soil temperature

Question 14

A researcher finds that seeds from the north side of a mountain grow taller than those from the south side, even when planted in the same environment. What is the most likely explanation?

Accepted Answer

Genetic differences due to evolutionary history

Question 15

Which of the following is a correct statement about the photic and aphotic zones in aquatic biomes?

Accepted Answer

The photic zone receives enough light for photosynthesis

Question 16

Which of the following best describes an ecotone?

Accepted Answer

A region of transition between two biomes

Question 17

Which process is most responsible for the formation of wet and dry seasons in tropical deciduous forests?

Accepted Answer

Shifting angle of the sun during Earth's annual orbit

Question 18

Which of the following is a plausible effect of deforestation on local climate?

Accepted Answer

Increased surface temperatures and decreased precipitation

Question 19

Which of the following equations best represents the relationship between sunlight intensity and latitude?

Accepted Answer

$$I = I_0$ \cos(\theta)$$, where $$I is $$intensity and $$\theta is $$the angle from the vertical
