Algae also live in panels inside giant clams and in sponges and flat worms. An example of a marine ecosystem is a coral reef, with its associated marine life — including fish and sea turtles — and the rocks and sand found in the area. The average rate of primary production in the open ocean is 125 gC/m2/yr. A marine ecosystem is any that occurs in or near salt water, which means that marine ecosystems can be found all over the world, from a sandy beach to the deepest parts of the ocean. 2San Francisco Bay Regional Water Quality Control Board Epizoic- algae grow on the outer surface of the animal body. It is very important that you sanitize your tanks regularly. These systems contrast with freshwater ecosystems, which have a lower salt content. The marine setting is the domain of the phytoplankton, a taxonomically diverse assemblage of microscopically small, unicellular algae, drifting freely in the water column , Phytoplankton species can grow and multiply rapidly, fuelled by nothing else than sunlight, nutrients and CO 2.

Ships also create noise pollution that disturbs natural wildlife, and water from ballast tanks can spread harmful algae and otherinvasive species. They are in a group called cyanobacteria and are more closely related to bacteria. Algae also provide important habitats for invertebrates and fish. With few exceptions,they have eschewed the strong, stiff armor typical of nearshore sessile animals and are constructed instead of weak, compliant materials. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems, and is often recognized by the discoloration in the water from their pigments. Some types of marine algae are considered a nuisance. RED TIDE: Red tides are a marine phenomenon in which water is stained a red, brown, or yellowish color because of the temporary abundance of a particular species of pigmented dinoflagellate (these events are known as “blooms”). Various types of algae-eating marine snails and blennies would clean the algae in nano tanks, and some bulkier fish and slugs could eat the stuff in larger tanks. Diatoms are easily to combat. All of these species are insignificant, nonmotile spheres which do not direct any dissimilar morphological feature and cannot be made eminent through either light or electron microscopy. For example, Cyanobacteria species, like red slime algae, prefer low current areas, while most hair/filamentous species prefer high current areas. 1, and Jeffrey S. Brown.

Pronunciation: Algae ("al'jay" or "al'gay", both are used today) is the plural; Alga ("al'ga") is the singular, but here is no such thing as "algaes". Green algae can be found in marine or freshwater habitats, and some even thrive in moist soils. Example: Nannochloropsis. Severe algal growth blocks light that is needed for plants, such as seagrasses, to grow. A number of freshwater green algae (charophytes, desmids and Spirogyra) are now included in the Charophyta (charophytes), a phylum of predominantly freshwater and terrestrial algae, which are more closely related to the higher plants than the marine green algae belonging to the Chlorophyta (known as chlorophytes). deposit. Marine Algae are organisms that are able to carry out the process of photosynthesis; using energy provided by the sun light . Algae are widely distributed in the aquatic environment. The length of Phaeophyta can range from a microscopic length to several meters.
