Marine Ecosystem

Why doesn’t photosynthesis occur in deep ocean water?

• The water temperature is too cold

• There is no sunlight

• There are not enough nutrients

• The salinity level of the water is too high

True of False: The temperature of the ocean water decreases as the depth of the water increases.

• True

• False

Both the arctic and antarctic ecosystems...

• have penguins as intermediate predators.

• have polar bears as top predators.

• have plankton at the base of the food chain.

• have large amount of land area with plants.

The population density of marine life is greater along the shorelines of the ocean than farther out in the deep waters of the ocean. Which statement provides the best reason for this situation?

• Ocean currents prevent many smaller marine organisms from living in deep water.

• The shallow waters have fewer predators.

• Coastal waters are less polluted than the deeper waters of the ocean.

• There are more nutrients in shallow waters.
