Which best describes the relationship between temperature and dissolved oxygen in a lake?

• As temperature increases, dissolved oxygen increases.

• As temperature increases, dissolved oxygen decreases.

• As temperature decreases, dissolved oxygen decreases.

• A change in temperature has no effect on dissolved oxygen.

Which characteristic of an estuary makes it a good nursery area for marine organisms?

• It is located at the mouth of a river.

• It has a mix of salt and fresh water.

• It has many areas to hide from predators.

Which best explains the importance of estuaries?

• Estuaries are freshwater areas that support a large amount of living things.

• Estuaries are areas where freshwater and salt water collide, resulting in a large amount of biodiversity.

• Estuaries are tropical areas that support an abundance of life found usually in cold regions of the ocean.

• tuaries are nutrient-rich areas because they have large amounts of carbon dioxide seeping into the water from the ground below.
