Aquatic ecosystem notes pdf Continue Habitat is part of the ecosystem. Climate, plants and animals are the identity of the habitat. Ecosystems mainly have two areas: the terrestrial or land ecosystem of the aquatic or aquatic ecosystem. Water supports many lives. Organisms that survive in water are called aquatic organisms. They depend on water for their nutrition, shelter, reproduction and all other activities of life. The aquatic ecosystem includes a group of interacting organisms that depend on each other and their aquatic environment for nutrients and shelter. Examples of the aquatic ecosystem are oceans, lakes and rivers. The aquatic ecosystem includes freshwater habitats such as lakes, ponds, rivers, oceans and streams, wetlands, marshes, etc., and marine habitats include oceans, inter-tinge zones, reefs, seabeds and so on. The aquatic ecosystem is a habitat for water-dependent living species, including animals, plants and microbes.

Fresh water includes lakes, ponds, rivers and streams, wetlands, swamps, swamps and temporary pools. Freshwater habitats are classified into lotto and sloth habitats. Water bodies such as lakes, ponds, pools, swamps and other reservoirs are standing water and are known as sloth habitats. While many habitats are leaking bodies of water, such as rivers and streams. They are mainly fast-flowing waters that move in a one-way manner, including rivers and streams. These conditions are home to many insect species such as beetles, maifley, stone birds and several species of fish, including trout, eel, flesh, etc. They include all standing water habitats. Lakes and ponds are the main examples of a lean ecosystem. The word lenty mainly refers to stationary or relatively stationary water. These ecosystems are home to algae, crabs, shrimp, amphibians such as frogs and salamanders, both for root vegetables and floating storm plants and reptiles including alligators and other water snakes are also found here. Wetlands are marshy areas and are sometimes covered with water, which has a wide variety of plants and animals. Swamps, swamps, marshes, black spruces and water lilies are some examples in plant species found in wetlands. The animal life of this ecosystem consists of dragonflies and damselflies, birds such as the Green Heron and fish such as the Northern Pike. Marine aquatic ecosystem marine ecosystem covers surface area of the Earth. Two thirds of the land is covered with water and consists of oceans, seas, bathydal zone, reefs, seabed, estuaries, hydrothermal vents and rock basins. Each life form is unique and native to This is because they have adapted according to their habitat. In the case of aquatic animals, they cannot survive outside the water. Exceptional cases still there show another example of devices (e.g. mudskippers). The marine ecosystem is more concentrated with salts, which make it difficult for freshwater organisms to live in. Their body is adapted for living in salt water; If they are placed in less salty water, their body will swell (osmosis). Our planet Earth is endowed with five main oceans, namely the Pacific, Indian, Arctic and Atlantic oceans. Among all these five oceans, the Pacific and Atlantic Oceans are the largest and deepest ocean. These oceans are home to more than five lakh aquatic species. Few creatures of these ecosystems include molluscs, sharks, tubular worms, crab small and large ocean fish, turtles, crustaceans, blue whales, reptiles, marine mammals, seabirds, plankton, corals and other ocean plants. These are open land and water systems that combine to form coastal ecosystems. Coastal ecosystems have different structure and diversity. At the bottom of the coastal ecosystem is home to a wide range of species of aquatic plants and algae. The fauna is diverse and consists mainly of crabs, fish, insects, lobster snails, shrimp, etc. Plants and animals in the aquatic ecosystem show a wide range of adaptations that can include life cycle, physiological, structural and behavioral adaptation. Most aquatic animals are ordered, which helps them reduce friction and thus save energy. The fins and gills are locomotives and respiratory organs respectively. Features in freshwater organisms help them to drain excess water from the body. Water plants have different types of roots that help them survive in the water. Some of them may have underwater roots; some have appeared roots or maybe floating plants like water hyacinths.

Communities of organisms dependent on each other and on the environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. Types of Marine Main Article: Marine Ecosystem Marine Ecosystem, the largest of all ecosystems, covers about 71% of the Earth's surface and contains about 97% of the planet's water. They generate 32% of the world's net primary production. They differ from freshwater ecosystems by the presence of dissolved compounds, especially salts, in water. Approximately 85% Sodium and chlorine are found in seawater. Sea water has an average salinity of 35 parts per thousand water. Actual salinity varies depending on different marine ecosystems. Classification of marine habitats. Marine ecosystems can be divided into many zones depending on the depth of the water and the features of the coastline. The oceanic zone is a vast open part of the ocean where animals such as whales, sharks and tuna are inhabited. The bent zone consists of substrates under water, where many invertebrates live. The tidal zone is the area between the tides; in this image it is called coastal zones. Other coastal (non-synthetic) zones may include estuaries, salt marshes, coral reefs, lagoons and mangrove swamps. In deep water, hydrothermal vents may occur, where chigiosintetic sulfur bacteria form the basis of the food web. Classes of organisms inhabited in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms and sharks. Fish caught in marine ecosystems are the largest source of commercial products derived from wild populations. Environmental problems related to marine ecosystems include unsustainable exploitation of marine resources (e.g. overfishing of some species), marine pollution, climate change and coastal construction. The main article on fresh water: freshwater ecosystem freshwater ecosystem. Freshwater ecosystems cover 0.78% of the Earth's surface and inhabit 0.009% of its total water. They produce almost 3% of their net primary production. Freshwater ecosystems contain 41% of the world's known fish species. There are three main types of freshwater ecosystems: lenty: slow-moving water, including pools, ponds and lakes. Lotik: faster moving water, such as streams and rivers. Wetlands: Areas where soil is saturated or flooded, at least part of the time. Lentic See also: Lake Three ecosystem is the main lake area. Lake ecosystems can be divided into zones. One common system divides lakes into three zones (see picture). First, the coastal zone is a shallow zone near the coast. This is where the roots of wetland plants occur. The sea shelf is divided into two zones, an open water zone and a deep-sea zone. In an open water zone (or photic zone), sunlight supports photosynthetic algae and the species that feed on them. In the deep-sea zone, sunlight is not available, and the food web is based on detritus coming from coastal and photic zones. Some systems use other names. Offshore areas can be called a pelagic zone, the photo zone can be called a lymphatic zone, and the apostic zone can be called a pro-und. Inland from coastal areas can also often identify the Riparian zone, which plants still From the presence of the lake- this may include the effects of unforeseen circumstances, spring flooding, and damage to winter ice. Manufacturing The lake as a whole is the result of the production of plants growing in coastal areas, combined with the production of plankton growing in open water. Wetlands can be part of the sloth system because they naturally form along most of the lake's shores, the width of wetlands and coastal areas depends on the slope of the shoreline and the number of natural changes in water levels over and between years. Often dead trees accumulate in this area, either from unforeseen circumstances on the shore or logs, transported to the site during floods. This tree litter provides an important habitat for fish and nesting birds, as well as protecting coastlines from erosion. The two important subclasses of lakes are ponds, which are usually small lakes that are intertwined with wetlands and reservoirs. Over long periods of time, lakes or bays in them can gradually be enriched with nutrients and slowly filled with organic sediments, a process called continuity. When people use the watershed, the amount of precipitation entering the lake can speed up the process. Adding sediments and nutrients to the lake is known as eutrophication. Ponds are small reservoirs with shallow and shallow water, swamps and aquatic plants. They can be divided into four zones: vegetation area, open water, upable mud and surface film. The size and depth of ponds often vary greatly depending on the time of year; many ponds are produced as a result of spring flooding of rivers. Food networks are based on both free-floating algae and aquatic plants. There is usually a wide range of aquatic life, with several examples including algae, snails, fish, beetles, water beetles, frogs, turtles, otters and muskrats. The best predators can include large fish, herons or alligators.
