BL 1300 February 2013 Aquatic Ecosystem Function An ecosystem can be defined as “all the organisms in a given area as well as the abiotic factors with which they interact” (Reece et al. 2010). Common aquatic ecosystems range from the largest oceans to the smallest creeks‚ but each aquatic ecosystem plays a pivotal role in global ecology. Each ecosystem consists of important aspects including nutrients cycling‚ biodiversity‚ and energy flow that contribute to the overall state of the ecosystem

The ecosystem group chosen is a local‚ coastal ecosystem called the Barker Inlet – St Kilda Aquatic Reserve and the Torrens Island Conservation Park. Together we have termed them the Barker Inlet Mangrove Ecosystem which is situated approximately 20 kilometres north west of Adelaide (see figure 1) and covers an area of approximately 20.5 kilometres

Conserving biodiversity is a very important task as a human. We must help keep the organisms and living things intact. A rainforest is the perfect example of how we currently keep this environment friendlier and healthier. Ethics‚ the study of ecology‚ economics‚ and aesthetics can explain why we conserve biodiversity. As we begin to kill species‚ we have to remember that each species has a right to life. We also have to take into consideration that we are being selfish when we kill off rainforest

Description of biological or chemical processes that can occur only in presence of oxygen. Anaerobic - Life processes or chemical reactions that occur in the absence of oxygen or a condition in which Dissolved Oxygen (DO)‚ is not detectable in the aquatic environment. Available residual Chlorine - Generally refers to the part of the chlorine that will with orthotolidine or ampero-metric tests and exhibits significant germicidal activity. Bottled water - means water that is placed in a sealed container

Chapter 50 Ecology is the scientific study of the interactions between organisms and their environment. Concept 50.1 Ecology is the study of interactions between organisms and the environment Ecology and evolutionary biology are closely related sciences. * Ecology has a long history as a descriptive science. * Modern ecology is also a rigorous experimental science. * Ecology and evolutionary biology are closely related sciences. * Events that occur over ecological time (minutes

Pulicat Lake is the second largest brackish water lagoon after Chilika Lake of Orissa along the east coast of India. Estuaries and lagoons have brackish water which shows high biological productivity than fresh or sea water. Hence it has wide range of aquatic‚ terrestrial flora. The World Wide Fund for Nature declared it as a protected area. Present study aims to explore the flora of the lagoon along with the various threats for its eco-degradation which helps to plan necessary conservation methods. Key

implemented by the government and to test whether the laws are being implemented strictly or not. There are four major problems encountered in the preservation of marine biodiversity. According to Department of Agriculture-Bureau of Fisheries and Aquatic Resources (2004) the main problems encountered in the preservation of the country’s marine biodiversity are Overfishing‚ Pollution‚ Deforestation‚ and Global climate change. Overfishing or over exploitation is the removal of marine living resources
