Multiple choice

What is the term used to describe the study of the distribution and abundance of aquatic organisms?

  1. Biogeography

  2. Population Ecology

  3. Community Ecology

  4. Ecosystem Ecology
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biogeography is the study of the distribution and abundance of aquatic organisms in relation to their environment.

Multiple choice

Which of the following is NOT an example of an ecosystem service?

  1. Pollination of crops by insects

  2. Purification of water by wetlands

  3. Production of oxygen by forests

  4. Extraction of fossil fuels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Extraction of fossil fuels is not an ecosystem service because it does not provide any benefit to the environment. In fact, it can be harmful to the environment, as it can lead to pollution and climate change.

Multiple choice

Which ecosystem service is responsible for providing us with food?

  1. Pollination

  2. Water purification

  3. Climate regulation

  4. Food production
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Food production is an ecosystem service that provides us with the food we need to survive. This service is provided by plants, animals, and microorganisms that produce food through photosynthesis, respiration, and decomposition.

Multiple choice

Which ecosystem service is responsible for regulating the Earth's climate?

  1. Pollination

  2. Water purification

  3. Climate regulation

  4. Food production
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Climate regulation is an ecosystem service that helps to regulate the Earth's climate by absorbing and storing carbon dioxide, releasing oxygen, and reflecting sunlight.

Multiple choice

Which of the following is an example of a regulating ecosystem service?

  1. Pollination

  2. Water purification

  3. Climate regulation

  4. Food production
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Climate regulation is an example of a regulating ecosystem service because it helps to regulate the Earth's climate by absorbing and storing carbon dioxide, releasing oxygen, and reflecting sunlight.

Multiple choice

Which of the following is an example of a supporting ecosystem service?

  1. Pollination

  2. Water purification

  3. Climate regulation

  4. Soil formation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil formation is an example of a supporting ecosystem service because it provides the foundation for all other ecosystem services. Soil is formed by the weathering of rocks and minerals, and it is essential for plant growth.
