Multiple choice

What is the term used to describe the functional role of a species within an ecological community?

  1. Ecological Niche

  2. Habitat

  3. Trophic Level

  4. Population Density
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Multiple choice

Which of the following is not a supporting service that contributes to habitat provision and maintenance?

  1. Soil formation

  2. Nutrient cycling

  3. Pollination

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

Predation is a regulating service, not a supporting service. Supporting services are those that create and maintain the physical structure of an ecosystem, while regulating services are those that regulate the flow of energy and matter through an ecosystem.
