most cases‚ indices only work well for the water bodies in the regions in which they were developed‚ and may give anomalous results in other types of water body. Biotic Indices The basis of any aquatic eco-system is water and the quality of the ecosystem may be determined by the quality of the water. Biotic indices can give an indication of the quality of the water. Biotic Indices‚ which are based on the presence or absence of particular indicator groups or species at the sampling point‚ are best

The word ecosystem refers to the combined physical and biological components of an environment; these organisms form complex sets of relationships and function as a unit as they interact with their physical environment. Ecosystems are constantly changing naturally‚ and they’ve got a specific and stable climax‚ equilibrium. Living as well as non-living factors may have an impact in an ecosystem such as the impact of humans in ecosystems by hunting‚ fishing‚ agriculture etc. or climate change

The Field Studies of the Mangrove Ecosystem at Bicentennial Park It might be said “Bicentennial Park is a diverse natural property”(1) which studies the ecosystem of mangroves‚ saltmarsh and other biotic and abiotic factors. Bicentennial Park is located in Sydney Olympic park‚ NSW Australia. “The state and federal government created the Park during 1980s‚ to celebrate Australia’s Bicentenary in 1988”(2). “On 1 January the Park was officially opened”(3). “This large

organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water that keep the ecosystem growing and balanced. A biome is a geographical

Acid Rain and its Effects On Our Aquatic Ecosystems In the past century‚ one of the greatest threats to North America ’s aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems‚ as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain‚ and what can be done to improve North America ’s water quality

This species was endemic to the United States. [pic] I didn’t manage to find any specific ecological role of Coosa Elktoe‚ however I found the ecological role of mussels. Mussels play a key role in aquatic environments and are considered to be "ecosystem engineers" because they modify aquatic habitat‚ making it more suitable for themselves and other organisms. One of the valuable functions performed by mussels is capturing organic matter from the water column when they siphon‚ processing it to build

Interactions and Interrelationships among the Different Components of the Ecosystem I. Introduction Ecology is the study of environmental systems‚ or as it is sometimes called‚ the economy of nature (Hall and Weiss‚ 2010). It studies interactions between different organisms and their environments‚ including relations within its own species and members of others. Ecology focuses more on the population‚ community‚ and ecosystem ecology although it also includes a wide variety of fields. Both

Species – A species is a group of organisms with similar characteristics‚ which can interbreed and produce viable‚ fertile offspring. Habitat – A habitat is the environment in which a species normally lives or the location of a living organism. Population – A population is a group of organisms of the same species‚ who
