KEY QUESTIONS  SWBAT explain what abiotic factors influence aquatic ecosystems.  SWBAT list the major types of aquatic ecosystems.  SWBAT describe the ecological roles of organisms in aquatic food webs.

ESTUARY Found where the fresh water of a river meets the salt water of the ocean.

INTERTIDAL ZONE The area between the highest high-tide line and the lowest low-tide line.

NERITIC ZONE Shallow region that extends over the continental shelf.

KELP FORESTS Grow in cold neritic waters where the bottom is rocky.

CORAL REEFS Created by colonies of tiny coral animals. One of the most diverse ecosystems in the world.

PLANKTON Tiny organisms that float in the water

FRESHWATER ECOSYSTEMS Includes: Streams

FRESHWATER ECOSYSTEMS Includes: Streams, Rivers

FRESHWATER ECOSYSTEMS Includes: Streams, Rivers, Ponds

FRESHWATER ECOSYSTEMS Includes: Streams, Rivers, Ponds, and Lakes

MARINE ECOSYSTEMS Depends largely by the depth of the water.

OCEAN FOOD WEB Depends largely by the depth of the water.

KEY QUESTIONS  What abiotic factors influence aquatic ecosystems?

KEY QUESTIONS  What abiotic factors influence aquatic ecosystems?  All aquatic ecosystems are affected by the same abiotic factors: sunlight, temperature, oxygen, and salt content.

KEY QUESTIONS  What abiotic factors influence aquatic ecosystems?  All aquatic ecosystems are affected by the same abiotic factors: sunlight, temperature, oxygen, and salt content.  What are the major types of aquatic ecosystems?  Freshwater ecosystems include streams, rivers, ponds, and lakes.  Marine ecosystems include estuaries, intertidal zones, neritic zones, and the open ocean. These zones are classified largely by the depth of water.

But in the ocean, the producers are algae rather than plants.
