Many species though are microscopic, unicel- lular, or colonial organisms that live in planktonic or sessile aquatic habitats and are reported infrequently from few localities. Thermophilic Algae - These live in hot springs. This is a collective name for a varied group of phyla with no one diagnostic feature.

The two main types of aquatic ecosystems are marine ecosystems and freshwater â¦ Aquatic Algae: Aquatic algae may be fresh water (when salinity is as low-as 10 ppm) or marine (when salinity is 33-40%). Harmful algal blooms in Oceans: Pfiesteria Coast of Carolinas Floating microrganisms that thrives in nutrient conditions Highly toxic to fish and humans Blue-green algae bloom August 2003 Microcystis A toxic blue-green alga Microcystis bloom covers 600 sq. Many coloured pigments such as green, red, yellow, and blue have been found in marine and freshwater algae. Population growth of Humans Increasing population means greater demand for food, shelter, fuel and water. They are chlorophyllous thus autotrophic, with simple thallus and lacks tissue differentiation. 1. An aquatic ecosystem is an ecosystem in a body of water.

Phytoplankton is made up of algae and small plants while zooplankton consists of animal organisms. Neustonic Algae - These grow on the water surface. In addition, the fossil record for some groups of algae has hindered evolutionary studies, and the realization that some algae are more closely related to protozoa or fungi than they are to other algae â¦ The genus Spirogyra comprises more than 300 species and most of them are free floating algae. km Coral Reef overgrowth Nutrients stimulate algae that cover coral\ Loose habitat â¦ Algae also dies very quickly, and the decay â¦ Bryophytes ... â A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - â¦ Invasive Species Any organism that has been relocated somewhere other than its original habitat. Salinities of 20â24 ppt are found to be optimal. Many are downloadable. egregia. Algae of remarkable habitats. Nutrients like phosphorous contribute to the spread of algae. They are found in different habitats from fresh to marine waters to extreme conditions. In general, this is an area between latitudes of 25 degrees north and 25 degrees south, however, geographical limits are highly variable depending upon the area of the world and local climates. â¢The current systems of classification of algae are based on the following main criteria: o kinds of photosynthetic pigments, o type or chemical nature of photosynthetic energy storage products o photosynthetic membranesâ (thylakoids) organization and other features of the chloroplasts. Algae are commonly presumed to be occurring in water and moist places but algae are found in a variety of habitats. Unicellular algae occur most frequently in water, especially in plankton.Phytoplankton is the population of freeâfloating microorganisms composed primarily of unicellular algae. When a freshwater habitat has a sharp increase in phosphorous, algae âblooms,â or reproduces quickly. Climate change is altering key habitat elements that are critical to wildlife's survival and putting natural resources in jeopardy. Terrestrial algae, and . They need the right temperatures, fresh water, food sources, and places to raise their young. According to the Whittaker scheme, algae â¦ Edaphic Algae - These live on or in soil. analipus. ... Volvox. All of these organisms possess the photosynthetic pigment chlorophyll- You can find algae in a variety of habitats such as freshwater, marine, moist stones, wood, and even soil. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. Algae is a microscopic aquatic organism that makes its own food through the process of photosynthesis. Cladophora is a cosmopolitan alga and can be found in huge masses of a variety of marine and fresh waters, which provide habitat as well as food for numerous organisms (Dodds and Gudder, 1992). Wildlife depends on healthy habitats. Algae - Algae - Evolution and paleontology of algae: Modern ultrastructural and molecular studies have provided important information that has led to a reassessment of the evolution of algae. Get ideas for â¦ Freshwater red algae are largely restricted to streams and rivers b ut also can occur in other inland habitats, such as lakes, hot â¦ In artificial culture, most grow best at a salinity that is lower than that of their native habitat.
