Question 2

A scientist is studying the effect of a new predator on the population size of a specific fish species in a lake. Which level of ecological study does this research best represent?

Accepted Answer

Population ecology

Question 3

Which of the following is an example of an abiotic factor that can limit the distribution of a species?

Accepted Answer

Salinity

Question 4

The Coriolis effect is responsible for which of the following phenomena?

Accepted Answer

The deflection of global wind patterns due to Earth's rotation

Question 5

Which equation correctly represents the change in population size ($$\Delta N) $$over a time interval ($$\Delta t$$), ignoring immigration and emigration?

Accepted Answer

$$\Delta N = B - D$$

Question 6

A population of rabbits in a field increases rapidly at first, but then the growth rate slows as resources become limited. Which model best describes this population growth?

Accepted Answer

Logistic growth model

Question 7

Which of the following best explains why deserts are often found on the leeward side of mountain ranges?

Accepted Answer

Warm, moist air rises and releases moisture on the windward side, leaving dry air to descend on the leeward side

Question 8

Which of the following is a characteristic of a Type III survivorship curve?

Accepted Answer

High death rates for juveniles and lower death rates for survivors

Question 9

Which of the following is a direct consequence of the Earth's tilt and its annual passage around the sun?

Accepted Answer

Seasonality in temperature and day length

Accepted Answer

Oligotrophic

Question 11

Which of the following best describes the Intermediate Disturbance Hypothesis?

Accepted Answer

Species diversity is highest at moderate levels of disturbance

Question 12

Which of the following is a plausible reason why a species is absent from a suitable habitat?

Accepted Answer

The species has not dispersed to the area

Question 13

Which of the following is an example of a biotic factor that can limit the distribution of a plant species?

Accepted Answer

Herbivory by insects

Question 14

Which of the following best describes the photic zone in an aquatic biome?

Question 16

A population of birds is found to have a uniform dispersion pattern. Which of the following is the most likely explanation?

Accepted Answer

Individuals are territorial and defend spaces from each other

Question 17

Which of the following is a likely consequence of deforestation on local climate?

Accepted Answer

Higher surface temperatures and reduced precipitation

Question 18

Which of the following best describes r-selected species?

Accepted Answer

Question 19

Which of the following is a real-world example of a mutualistic relationship in an aquatic biome?

Accepted Answer

Corals and symbiotic algae in coral reefs

Question 20

A population of insects is being studied. The researchers find that the number of individuals per unit area is increasing due to a high birth rate and immigration. Which term best describes this property?

Accepted Answer

Density
