Use your assigned marine ecosystem description and illustration to decide which abiotic factors are impacting the organisms in your ecosystem. Place check marks next to those factors in the chart attached. Then write one or more examples of how that factor is impacting organisms in the ecosystem.
Changing tides cause changes in the rocky shore area, making the rocky shore one of the most physically stressful ecosystems. Organisms that live along the rocky shore must be able to tolerate extreme changes in temperature, salinity, and wave action.
Corals are made up of tiny animals called polyps. Relatives of sea anemones and jellyfish, polyps are tiny, translucent organisms with a hard base called a calicle. Calicles form the hard structure of a coral reef. Some corals contain a single polyp, bust most are colonial corals that contain thousands of polyps.
Ocean currents play an important role in the open ocean community. Open ocean currents carry nutrients to different parts of the ocean. Currents also help some animals migrate and allow others to distribute their eggs throughout the ocean.

| Abiotic Factor | Examples | Abiotic Factor | Examples | Abiotic Factor | Examples | ||
| Temperature | x | certain plants cant survive in certain temperatures | x | different fish require a certain type of tempature | x | some sharkes need colder water | |
| Salinity | x | the rocky shore is affected by freshwater runoff | x | the coral is largely affected by the salt level | x | it affects the fish's environment | |
| Nutrients | x | many algae eaters and other similar organisma live in the rocky shore and need nutrients | x | plentiful organisms that require all types of nutrietnts to survive | x | living organisms need to have a constant source of food | |
| Oxygen | |||||||
| Solar Energy | x | plants in the rocky shore need to use the sun for photosynthesis | x | Coral and other algea types rely on the sun for energy | x | organisms such as alage need the sun for food | |
| Water Clarity | x | Fish that live in this area need to see to eat, move, etc. | |||||
| Tides | x | if the tide gets too low, an organism such as the starfish might get stranded | x | tides can affect fish's envornment/ movement of schools | |||
| Waves | x | waves bring new organisms and substances to the rocky shore | |||||
| Substrate | x | waves are constantly moving sand creating mounds | |||||
| Aerial Exposure | x | ||||||
| Currents | x | control certain patterns of the fish |

Rocky shore community
1 tempeture= tempeture would make the water warmer and it would give some organisms a heat problem.
2. The intake of salt would help the sea life breath easer bad it would help maintain the clearness of the water.
3. Nutrients. Organisms would be eaten by other organisms and this would help conserve energy.
4. Oxygen would help the land animals breathe and would help them survive on land.
5 solar energy gives all if the wild life a warm tempeture and helps them survive more efficient.
6 water clarity is perfect for the wild life so they can see the perfectly and so they can find their pray.
