[|Classification of Marine Organisms]Title:Classification of Marine Organisms

Explanation of Topic (Definition, Key Points, Details) Marine organisms can be classified according to where they live and how they move. Classification is also used to show how organisms are related to each other and to group them by their characteristics, but this can be diffucult for some marine organisms.THere are also six kingdims of marine organisms and this is what they are: Now in the textbook on page 428-429 there are three types of organisms and they are:
 * 1) Bacteria- Are single celled organisms that reproduce by spliting apart, they play a cruical role in ecosystems breakign down organic material and making nutrients aviable for the phytoplankton.
 * 2) Protozoans- single cell much larger than bacteria. They may be autotrophic or heteropic. In an Marine enviroment, this kingdom is well represnted and includes amoebae.
 * 3) Chromists- range from very small organisms suchas diatoms (type of plankton) to seaweed. Most chromists photosynthesis but are some signicfant differences that have led to classify then seperatly to plans they use a diff kind of chlorophyll.
 * 4) Fungi- they rely on breakign down organic material as they are not able to make their own food. There are very few fungi in marine organisms.
 * 5) Plants- multi-celler and autotrophic they use photosynthesis to produce food using sunlight plants. are more widespread on land and in freshwater and there are only a few types that thrive in marine environment, for example, eel grass and mangroves. Seaweeds were previously classed as plants before they were reclassified as chromists.
 * 6) **Animals** are typically large and multi-cellular. They are heterotrophic and rely on other organisms for food. Animals in the marine environment include jellyfish, sponges, sea spiders, bryozoans, mussels, sea stars, fish and whales.
 * 1) Plankton- which they include all organisms -algae, animals, and bacteria,- that drift with ocean currents. Just because they drift does not mean they can not swim some swim very weakly or just swim vertically. Among plankton, algae that undergo photosynthesis are called phytoplankton. Most phytoplankton, are microscopic. Animal plankton, are called zooplankton.
 * 2) Nekton- are all animals capable of moving independently of the ocean currents, by swimming or other means of propulsion. They are allowed to determine their position within the ocean and in many complete long migrations. Mainly include adult fish and squid marine mammals and marine reptiles. Fish appear everywhere in the ocean but mainly appear in abundant areas near continents and islands and in cold waters.
 * 3) Benthos- describes organisms living on or in the ocean bottom. Most benthos organisms live in shallow coastal floor contains a wide varietty of physical conditions and nutrient levels.
