Freshwater ecosystems include three general categories: rivers and streams, lakes and ponds, and freshwater wetlands. Which of the following describes freshwater wetlands, but not the other two categories? Select all correct answers.

• The ecosystem soaks up heavy rainfall, which helps to prevent flooding.

• Water flows in one direction only through the ecosystem.

• Water may cover the soil or lie just under the surface, for at least part of the year.

• The ecosystem may be a freshwater bog, a marsh, or a swamp.

Estuaries serve which important role for marine ecosystems?

• providing spawning and nursery grounds for many marine animals

• adding oxygen to the ocean water

• removing carbon dioxide from the ocean water

• removing salt from the ocean water

A team of deep-sea divers and biologists is exploring the open ocean. As team members dive downward from the surface, they observe significant changes to the ocean community at a depth of about 200 meters. What is the main cause of the changes at this depth?

• loss of brightness of the water

• increasing salinity of the water

• increasing temperature of the water

• decreased oxygen concentration of the water
