Kelp beds
Microscopic algae
Seagrasses
Mangroves
Question 2(Multiple Choice Worth 2 points)
(4.06 MC)Which statement best compares coral reef ecosystems to demersal ecosystems?

Coral reef ecosystems have high levels of nutrients in the water, and demersal ecosystems do not.
Coral reef ecosystems are typically in shallow water, and demersal ecosystems can exist at any depth.
Coral reef ecosystems can support large fish like sharks and rays, and demersal ecosystems cannot.
Coral reef ecosystems may have starfish, clams, and other invertebrates, and demersal ecosystems have only fish.
Question 3(Multiple Choice Worth 2 points)
(4.06 HC)Resident orcas live in coastal waters, while offshore orcas live in the open ocean and have a larger geographic range. The table below shows the top three threats to orca populations.

Table1. Factors considered in listing and potentially affecting recovery of Southern Resident killer whales.
Threat Listing Factors Severity Likelihood Feasibility of Mitigation
Prey availability Habitat High High High, many salmon recovery efforts underway
Contaminants Habitat, Inadequacy of Existing Regulations High High Medium, Puget Sound clean-up efforts underway
Vessel effects (commercial, recreational whale watch) Habitat, Overutilization, Inadequacy of Existing Regulations High High High, whale watching guidelines and outreach underway, NOAA evaluating regulations and/or protected areas

What prediction can you make about the impact of these threats on the resident populations versus the transient populations?
The resident populations are more likely affected by these threats because of their proximity to shore.
The resident populations and the transient populations are likely to be equally affected by these threats.
The transient populations are more likely affected by these threats because of their distance from shore.
Neither the resident populations nor the transient populations are likely to be affected by these threats in the future.
Question 4(Multiple Choice Worth 2 points)

A population is a group of the same species that all live in a particular area together.
A population is a group made up of different species that all live in a particular area together.
A population is a group of the same species that are spread out in different ecosystems and do not interact.
A population is a group of different species that are spread out in different ecosystems and do not interact.
