Decomposers are an important component of the marine ecosystem, as they break down dead organisms and release nutrients from these organisms back into ocean. Rocky shores are home to some of the most biologically diverse and productive communities throughout the world. They get eaten by fish. Detritus and Plankton Plankton are also like Detritus, but they are a little bit smaller. They also live on the surface of the ocean. Seastar Biology Taxonomy Life History Echinoderms Rocky Intertidal. Macroalgae are rare but will occur if hard surfaces such as shells or buried stones are available. The Rocky Intertidal Zone . Home. They are producers. Rocky Shore; Sandy Shore; ... Decomposers, including bacteria, complete the food chain by breaking down organic material and releasing it as nutrients and energy. It primarily grows along the eastern Pacific coast from Alaska to Baja California in dense forests, much like the rainforests on land. (1998). Rocky shore composition can range from large boulders to medium sized gravel and cobble; these features strongly influence the species that found at each location. 5, pp. Some decomposers in the ocean include fungi in the genera Lindra and Lulworthia, the bacteria Vibrio furnissii, shipworms, nematodes and amoebas. 629-644. Biotic factors would be things that have a biological component, i.e. Rocky shores are generally broken into the following zones based on the amount and type of inundation: Spray Zone, High Tide Zone, Middle Tide Zone, and Low Tide Zone . Sea anemones as secondary consumers on rocky shores in the south-western Cape, South Africa. sea otters herring gull tertiary consumers tertiary consumers carnivore carnivore niche: top predator and eats consumers niche: top predator and controls population Rocky shore food web food food food food shore crab food food secondary consumers food carnivore common prawn Marine biodiversity and trophic relationships define a variety of marine food chains and interconnect them in … The Study Introduction Methods Results Discussion Picture Gallery. producer-consUmer-decomposer kelp-Sea ottEr-Sea urchin. The animal populations on the rocky shore are dominated by invertebrates such as barnacles, mussels, oysters, tubeworms, limpets, chitons, snails, crabs and starfish.. Barnacles, mussels, and oysters are all stationary filter-feeders. These ecosystems lie at the interface between the land and the sea, exposing organisms here to alternating terrestrial and marine habitats in rhythm with the tidal cycle. Journal of Natural History: Vol. They are shrimp things that are alive or were alive. Photosynthesis is conducted by a microflora of bacteria, cyanobacteria, diatoms, and autotrophic flagellates living in the interstices between sand grains or attached to the surface of the grains. Bibliography and Weblinks Glossary The intertidal zone is defined as the area between the high tidal mark and the low tidal mark. Detritus eat rotten food and they are decomposers. Although some overlap does occur, plants and animals are adapted to live in certain zones on the shore and each zone contains its own unique complement of organisms. They look like insects or bacteria. Kelp Kelp is a type of algae that lives in the Pacific Ocean, and uses photosynthesis.
