Question 2

A scientist is studying how flamingos select mates. Which level of ecological research does this represent?

Accepted Answer

Organismal ecology

Question 3

Which equation best represents the relationship between solar energy and temperature variation across latitudes?

Accepted Answer

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

Question 4

What is the primary cause of seasonality in middle to high latitudes?

Accepted Answer

Earth’s tilt and annual passage around the sun

Question 5

Which process is responsible for the cooling effect of forests on local climate?

Accepted Answer

Transpiration

Question 6

A mountain range creates a rain shadow. What is the expected climate on the leeward side?

Accepted Answer

Warm and dry

Question 7

Which biome is characterized by high animal diversity, vertical layering, and constant high rainfall?

Accepted Answer

Tropical rain forest

Question 8

What adaptation is most common in desert plants to reduce water loss?

Accepted Answer

C4 or CAM photosynthesis

Question 9

Which equation describes the rate of photosynthetic productivity in aquatic ecosystems?

Accepted Answer

$$NPP = GPP - R$$

Question 10

Which aquatic zone receives the most light and supports the highest photosynthetic activity?

Accepted Answer

Photic zone

Question 11

What is the main difference between oligotrophic and eutrophic lakes?

Accepted Answer

Eutrophic lakes are nutrient-rich and often have depleted oxygen in deeper layers

Question 12

Which biome is most likely to be destroyed by draining and filling for agriculture, resulting in loss of water purification and flood reduction?

Accepted Answer

Question 13

Which factor is most responsible for the northward shift of butterfly species ranges in Europe?

Accepted Answer

Global climate change

Question 14

Which equation best represents the relationship between precipitation and evaporation in the tropics?

Accepted Answer

$$P = E + T$$

Question 15

Which biome is maintained by frequent fires that kill woody plants and allow grasses to dominate?

Accepted Answer

Savanna

Question 16

What is the primary impact of human-induced nutrient enrichment in lakes?

Accepted Answer

Algal blooms, oxygen depletion, and fish kills

Question 17

Which biome is characterized by cold, clear, swift headwaters and warm, turbid downstream waters?

Accepted Answer

Stream and river

Question 18

Which equation would you use to estimate the change in average global temperature over a century?

Accepted Answer

$$\Delta T = T_{2100} - T_{1900}$$

Question 19

Which aquatic biome is most affected by overfishing, pollution, ocean acidification, and global warming?

Accepted Answer

Oceanic pelagic zone

Question 20

Which adaptation allows coniferous trees to survive in cold climates with heavy snow accumulation?
