  ESTUARY ECOSYSTEM ·        An Estuary or Translational water is an area where a freshwater river or stream meets the Ocean. ·     In Estuaries, the salty ocean mixes with a freshwater river, resulting in Brackish water (salinity varies between 0 - 35 ppt). Brackish water is somewhat salty, but not as salty as the ocean. ·        Examples of Estuaries are River mouths, Coastal bays, Tidal marshes, Lagoons and Deltas. ·       India has 14 major, 44 medium and 162 minor rivers drains into the sea through various Estuaries. LIFE IN ESTUARY ECOSYSTEM ·     Only certain types of plants and animals adapted to the “brackish” estuarine waters. Factors influencing the distribution of organism in an Estuary are its Salinity and the amount of Flooding. ·       In general, the Phytoplankton of estuaries are Diatoms, Dinoflagellates, Green algae and Blue-green algae. ·        Towards the Sea coast of the Estuaries, there are large Algae and Seagrasses. Near the mouth of the Rivers

  MARINE ECOSYSTEM ·        Marine ecosystems make up the largest aquatic system in the world covering more than 70 percent of the planet. ·        Marine ecosystems are considered to be the habitats that complete the large system from the shores to the dark sea floor. ·        Just like every other ecosystem in the world, the aquatic ecosystems rely on each other for maintaining a balanced Marine ecosystem. ·        The marine ecosystems are important to the world, because without them, the marine life would not have and protection from predators, which could eventually make the marine life go extinct. ·        Economically, marine systems support billions of dollars worth of capture fisheries, aquaculture, offshore oil and gas, and trade and shipping. TYPES OF MARINE ECOSYSTEM a)      Rocky shore ecosystem (contains small and large rocks) b)     Sandy beach ecosystem (Sandy beach) c)      Mangrove ecosystem (Mangrove trees are salt-tolerant plant species with roots

  FRESHWATER ECOSYSTEM ·        Freshwater ecosystem refers to the water found in Lakes, Ponds, Streams and any other body of water other than the sea. ·        Freshwater has less than one gram per liter of Dissolved solids, mainly Salts of which Sodium chloride. Plants and Animals living in freshwater would not usually be able to live in Salt water, because their bodies are adapted to a low-salt content. ·        Freshwater ecosystems are vulnerable to water pollution that arises from a range of human activities. They are also used as water supplies for human use. ·        The study of Freshwater Biology is called as Limnology. ·        Fresh water is not the same as potable water (or drinking water). Much of the earth's fresh water (on the surface and groundwater) is unsuitable for drinking without some treatment. Fresh water can easily become polluted by human activities or due to naturally occurring processes, such as erosion. ·        The place where Fresh and Sal

  ECOSYSTEM ·        A complex relationship between all the Living and Non-living things interact with each other is known as ‘An Ecosystem’ or ‘Biome’. ·        The term Ecosystem was coined in the 1935 by the British Botanists Roy Clapham and Sir Arthur Tansley. ·        The components of an Ecosystem are divided into two components.   1)      Abiotic components (Rocks, Temperature and Humidity).  2)      Biotic components (Plants, Animals, Microorganisms and other organisms). ·        The gleaming energy from the Sun is the basic source of energy in all the Ecosystems. ·        Ecosystems are the foundation of ‘Biosphere’ and maintain the natural balance of the earth. ·        The study of Ecosystem is called Ecology. FOUR TYPES OF ECOSYSTEM ·        Four major types of Ecosystem are 1)      Terrestrial ecosystem a)      Forest ecosystem b)      Desert ecosystem c)      Grassland ecosystem d)      Mountain ecosystem 2)      Fresh water ecosystem a)
