Q: Which equation best represents the relationship between temperature drop and elevation increase in mountain ranges?

$$\Delta T = -6$$^{\circ}$$C \times \frac{\Delta h}{1000\,m}$$

Question 1

Which of the following best explains the formation of a 'rain shadow' as shown in the first image?

Accepted Answer

Warm, moist air rises up the windward side, cools and releases precipitation, while dry air descends on the leeward side, creating arid conditions.

Question 2

Based on the second image, what is the primary effect of increased vegetation on local climate?

Accepted Answer

Lower temperatures and more precipitation due to increased transpiration and evaporative cooling.

Question 3

Which ecological level is most concerned with the interactions between different species, as illustrated in the image showing zebras and wildebeests at a lake?

Accepted Answer

Community ecology

Question 4

A bumblebee pollinating a flower (third image) is an example of which type of ecological interaction?

Accepted Answer

Mutualism

Question 5

Which biome is characterized by high annual rainfall (about 400 cm), high year-round temperatures, and intense competition for light, as shown in the sixth image?

Accepted Answer

Tropical rain forest

Question 6

What is the main reason coral reefs (fourth image) are restricted to shallow, warm waters?

Accepted Answer

Corals require high oxygen concentrations and a solid substrate for attachment.

Question 7

The expansion of the long-spined sea urchin (C. rodgersii) range in Australia (fifth image) is primarily due to which abiotic factor?

Accepted Answer

Rising water temperature

Question 8

Which equation best represents the relationship between temperature drop and elevation increase in mountain ranges?

Accepted Answer

$$\Delta T = -6$$^{\circ}$$C 	imes \frac{\Delta h}{1000\,m}$$

Question 9

Which factor is most likely to limit the distribution of photosynthetic organisms in aquatic biomes?

Accepted Answer

Light penetration

Question 10

Which of the following is a plausible consequence of deforestation on local climate, as shown in the second image?

Accepted Answer

Hotter and drier climate due to reduced transpiration and less evaporative cooling.

Question 11

Which of the following best describes the effect of ocean currents on terrestrial climate?

Accepted Answer

Currents flowing toward the equator carry cold water from the poles, cooling nearby land.

Question 12

Which process is responsible for the mixing of oxygenated and nutrient-rich water in lakes during spring and autumn?

Accepted Answer

Turnover

Question 13

Which of the following is a major human impact on wetlands?

Accepted Answer

Draining and filling wetlands, leading to loss of habitat and reduced water purification.

Question 14

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

Accepted Answer

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

Question 15

Which of the following is a characteristic adaptation of desert plants?

Accepted Answer

Reduced leaf surface area and C4 or CAM photosynthesis for water conservation.

Question 16

Which factor is most likely to cause vertical layering in terrestrial biomes such as forests?

Accepted Answer

Competition for light among plants.

Question 17

Which of the following is a plausible effect of global climate change on species distribution?

Accepted Answer

Species ranges shift toward higher latitudes or elevations as temperatures rise.

Question 18

Which of the following is a defining feature of oligotrophic lakes?

Accepted Answer

Low nutrient content and high oxygen levels.

Question 19

Which of the following is an example of an abiotic factor limiting species distribution?

Accepted Answer

Temperature extremes causing protein denaturation.

Question 20

Which of the following best describes adaptive radiation?

Accepted Answer

The rapid evolution of an ancestral species into many ecologically diverse species following long-distance dispersal.
