Quiz Answer Key and Fun Facts
1. Also known as 'K' what is the term for the maximum maintainable population of an area?

Answer: Carrying capacity

(K-N)divided by K. N is the population size. As N gets close to K, the growth rate slows to zero.
2. This type of biome (habitat) has very long cold winters, short warm summers and typically has acidic soils as a result of the cold temperatures and litter fall.

Answer: Taiga (Coniferous forests)

There are two types of taiga. High latitudes receive little precipitation, where as in the Pacific Northwest they can receive up to 40 cm.
3. What is 'an interacting group of individuals of the same species'?

Answer: Population

They use common resources and are regulated by the same natural occurrences.
4. Stability is the response of a community to disturbance. One type of response is resilience, which is the ability to recover. The other type of response is resistance which is the ability to avoid what?

Answer: change

Those that are better able to avoid change have a better chance of surviving.
5. A population's role in the community or the resources it uses is called its _____?

Answer: Niche

Niche includes where the population lives and functions.
6. Two species or populations are competing for the exact same resources, and one will eventually exclude the other. What is the technical term for this?

Answer: Competitive exclusion

One species will have a competitive advantage.
7. Predators can influence the structure of a community because their removal from the community causes a catastrophic change in the composition and structure of the rest of the community. What are the predators called because of this?

Answer: Keystone species

They prevent competitive exclusion and maintain diversity in this way.
8. In mutualism, (2 organisms of different species interacting with each other) who benefits?

Answer: Both species benefit

Wouldn't it be pretty silly to have a species interaction where both species were harmed? One example of mutualism is trees and their association with mycorrhizal fungi. The tree gets water and nutrients and the fungi get sugar. Flowering plants and pollination is another example.
9. Succession is triggered by a community altering disturbance. What type of succession (primary or secondary) is caused by glacial retreat?

Answer: Primary

Primary succession is defined as an extreme disturbance where all of the soil (nutrients) have been removed. This type of succession takes a longer time to return to its original state.
10. What is the single most important factor contributing to losing or creating endangered species?

Answer: habitat loss

Animals need enough room to survive, reproduce and room for their offspring to migrate to. With habitat loss, this is often not possible.
