1. LS4 Water Ecosystems Camille, Michael, Max, Kayla

2.  Plankton-organisms that drift freely in the water Ex: diatoms or producers  Nekton-second group includes the larger active swimmers in a body of water Ex: turtle  Benthos-third group of organisms that live on the bottom of a body of water Ex: oysters  Internal zone-shallowest part of ocean  Estuary-where freshwater feeds into salt water

3.  The organisms of water ecosystems are divided into three groups: plankton, nekton, benthos.  Like land ecosystems, biotic and abiotic factors determine the types of organisms that can survive in the water environment.   Fun Facts! About 97% of the Earth’s water is salt water. 3% of the Earth’s water is freshwater.

4.  Moving bodies of water are small, but fast.  Faster bodies of water tend to have more oxygen.  Top predators such as herons, bass, and turtles, eat frogs, birds and sunfish.  Grass-like plants, moss, and some shrubs, are found in wetlands.  Fun Facts  The zones of freshwater ecosystems are, shore, shallow water, open water, and the floor, which is the bottom.

5.  Neritic zone is shallowest part of ocean, where kelp and seaweed forests grow.  Oceanic zone is divided into bathyal zone and abyssal zone.  Bathyal zone is home to many consumers  Abyssal zone is further down, darker and colder because the sunlight is completely blocked.

6.  The estuary's change with the tides.  They contain salt marshes  Ocean fish come here to lay eggs. Fun Facts Bobcats are at the top of estuary food chain Salt marshes act as sponges for the estuary

7.  1. Vocab: What is the shallowest part of the ocean ecosystem?

9.  2. What is the third group of organisms that live on the bottom of a body of water?

11.  Name the 3 main parts of the standing fresh water.
