Transcript of Intertidal Zone Biome project

A picture of a California Intertidal Zone Producers: Phytoplankton
Choloryphyta (green algae)
Rhodophyta (Red Algae)
Phaeophyta (brown Algae) Impact from Human Activity Intertidal Zone Abiotic Moisture-the littoral zone of high and salt water, makes it hard for animals to adapt to very wet weather and very dry climate. Water movement-turbulence of the water makes this zone hard to survive in. GAMER FOR LIFE Primary Consumers: Mussels Clams
Barnacles Sea squirts
Polychaete limpets Snails Secondary consumers: Star fish
Crab plankton Tertiary Consumers: zooplankton seaweed worm Sea Otter
Sea urchins common prawn shanny Common dog whelk herring gull Acorn barnical Common limpet Succession Relationships Biotic factors: Some of the biotic factors in the intertidal zone are human impact, density of algae, population of: plants, fish, birds, worms, crustaceans, and mammals.

A keystone specie in the intertidal zone is the sea otter who eat large amounts of sea urchins and keep the intertidal zone healthy. If there is a large population of sea urchins in one area it will create a "urchin barren" because of how heavy grazers they are. The sea urchins eat algae, small fish, mussels and other things. The algae are eaten by primary consumers like mussels that are later ate by another consumer in the food chain. If there aren't sea otters to keep the population of sea urchins at a reasonable amount then some of the other consumers in the Intertidal zone will disappear because the things they eat will be consumed by the sea urchins. Preditor-prey: Mussels eat plankton and are later eaten by sea urchins. who are eaten by sea otters.
Competition: The different types on barnacles fight over territory. The chthamalus are limited to their territory because of the competition with the blanus in the lower tide and the climate in the higher tide.
Mutualism: If there a thick dense algae covering it protects fish and other living things from the harmful rays of the sun. Endangered species a Prediction to what might happen to the intertidal zone is that it may slowly disappear over time if people are continually disturbing the intertidal zone or hunting animals that are a keystone specie like the sea otters. If we leave it alone and let it grow naturally. then it will prosper and grow the it should be with out influence. By Kali and Austin Grey whales
they have been hunted for their meat that can cost up to $3000 per pound. as well as whale oil that is use to make things like nail polish, paint, lighting oil and many other things.
when the hunters found the small lagoons the grey whales where breeding it made it very easy for the hunters to kill or slaughter the whales.
they have been slowly recovering from the slaughtering and their population has been increasing.
They have been recently in the past few years taken off of the endangered list but they are still heavily protected from people who are killing whales today. So that they grey whales don't end up on the endangered list again. http://www.google.com/imgres?q=Intertidal+zone&num=10&hl=en&safe=active&biw=1280&bih=906&tbm=isch&tbnid=fHXHNlUwBjfpRM:&imgrefurl=http://hawaii.gov/dbedt/czm/initiative/wec/html/sea/marine/inter.htm&docid=KDstLqnS1-l6LM&imgurl=http://hawaii.gov/dbedt/czm/initiative/wec/html/sea/marine/images/yokohama5.jpg&w=300&h=225&ei=f_NlULK1CKjxyAH_g4Fw&zoom=1&iact=hc&vpx=997&vpy=120&dur=570&hovh=180&hovw=240&tx=186&ty=110&sig=106418815156810142563&page=1&tbnh=174&tbnw=215&start=0&ndsp=17&ved=1t:429,r:12,s:0,i:111
http://bagheera.com/inthewild/van_anim_grywhale.htm Cites: some Human impacts are such as taking shells out of the water which is illegal by doing so you kill some species that live or use the shells and they are often crushed or killed everyday Another abiotic factor includes the coping with wave shock, organisms must be able to withstand, or find shelter.
