Question 1

Based on the image, which of the following best describes the difference between community ecology and ecosystem ecology?

Accepted Answer

Community ecology examines all organisms in a particular area, while ecosystem ecology examines all organisms plus the abiotic factors in that area.

Question 2

Which level of ecological study is primarily concerned with the adaptations that enable individual organisms to meet the challenges posed by their environments?

Accepted Answer

Organismal ecology

Question 3

If a scientist is studying the effect of water temperature on the reproductive rate of a single fish species in a lake, which level of ecology is being investigated?

Accepted Answer

Organismal ecology

Question 4

Which of the following scenarios best represents population ecology?

Accepted Answer

Studying how a group of the same fish species interact and change in number over time in a coral reef.

Question 5

Which of the following is an example of a question that would be addressed by ecosystem ecology?

Accepted Answer

How do changes in water pH influence the diversity of all organisms and the cycling of nutrients in a coral reef?

Question 6

Which of the following best describes the hierarchical order of ecological study from least to most complex, as shown in the image?

Accepted Answer

Organismal ecology → Population ecology → Community ecology → Ecosystem ecology

Question 7

A researcher is interested in how the presence of both living coral and nonliving sand affects the distribution of fish species in a reef. Which level of ecology does this research most closely align with?

Accepted Answer

Ecosystem ecology

Question 8

Which of the following is NOT a focus of community ecology?

Accepted Answer

The effect of abiotic factors on all organisms in an area

Question 9

If a scientist is studying how a disease spreads through a group of the same fish species in a reef, which level of ecological organization is being examined?

Accepted Answer

Population ecology

Question 10

Which of the following best illustrates the concept of an ecosystem as shown in the image?

Accepted Answer

All the fish, coral, and other living organisms, plus the water, sunlight, and nutrients in a coral reef
