Patterns in a community. Community. Is all the organisms that live within a defined area and their interactions What are the 3 patterns you NEED to be aware of? Zonation, stratification, and succession http://www.youtube.com/watch?v=k-OOfW6wWyQ. Stratifiction.
Zonation, stratification, and succession
(i.e. exposure to sea water and air)
Periwinkles and barnacles (found at the top end), can glue themselves into a crevice or shut their trapdoors.
Seaweeds are found in the pools or lower down as they dry out.
e.g. Limpets and cats-eyes need to be covered with water before they can start eating
Green seaweeds highest, brown, and red is the lowest
Organisms higher up on the shore need to be able to fix themselves tightly to the rock e.g. barnacles, mussels, kelp (permanently) or periwinkles, chitons and limpets (temporarily).
