Our water science program emphasizes the fundamentals of all areas of science as they apply to water, with special emphasis on surface water and groundwater systems. UW-Green Bays four coastal campuses cover a unique geographic region of Wisconsin that provides hands-on research opportunities in surface water and groundwater that no other university can duplicate. The global need for water science professionals to solve critical water issues is accelerating and expected to continue indefinitely. Our professors are dedicated instructors and curious researchers. Students have first-hand opportunities to learn about the Green Bay estuary, Lake Michigan, the Fox River, groundwater chemistry in different aquifers, unique fisheries, coastal wetlands, and more. The waters of inland aquatic ecosystems are said to be largely freshwater with an exception of a few salty lakes. They are homes to significant proportion of world biodiversity and also play a central role in maintaining the balance of nature. Fish (finfish and shellfish) are important sources of protein to human b eing. For instance, they are important in hydropower generations, agricultural irrigations, navigations, drinking water suppl y, etc. Nowadays the global aquatic ecosystems, especially freshwaters, are being threatened due to over use and other human impacts. This, thus, calls for their proper utilization and management to allow them continue functioning sustainably. Thus, in order to mitigate the problem, knowledge of aquatic ecosystems and their dynamics is crucial. And this in turn calls for the incorporation of aquatic science and fishery courses in the curricula of higher learning institutions which has not been a case in Ethiopia so far. However, given the very short time to prepare and review the material, the writer would like to kindly request readers to reasonably forward their constructive comments for improvement to email addresses: m ulugeta.wakjiraju.edu.et or enku2005yahoo.com. The Writer A. This is a wa ter ecosystem that provides many vital environmental functions both to human being and other organisms. For example: They are important in nutrient recycling, flood attenuation and habitats provision to wildlife (biodiversity). The largest proportion of rainfall comes from evaporation of water bodies. They are also used for human recreation, and are very important to the tourism industry, especially in coastal regions. Aquatic ecosystems are composed of biotic communities (also called biota) and abiotic environmen tal factors, which form a self-regul ating and self- sustaining unit. The biotic components of aquatic ecosystems are either autotrophic or heterotrophic as described in chapter 3. Activity: What is the difference between autotrophic and heterotrophic organisms in aquatic habitats Give examples. Dxf file polyline exampleAbiotic environmental factors of aquatic ecosystems include the amoun t of dissolved oxygen (DO), temperature, amount of light, salinity, pH, nutrie nts such as nitrogen (in the form of mainl y nitrates) and phosphorus (in the form of phosphates). Refer to s ection 5.2.1. The amount of dissolv ed oxygen in a water body is frequently the key substance in determining the extent and kinds of organic life in the water body. Conv ersely, ox ygen is fatal to many kinds of an aerobic bacteria. The salinity of the wat er body is also a determining factor in the ki nds of s pecies found in the water body. Organisms in marine ecosystems tolerate salinity, while many freshwater or ganisms are intolerant of salt. Freshwater used for irrigation purposes often absorb levels of salt that are harmful to freshwater organisms. What do you call them What are the major differences that lie among the three There are three major types of aquatic ecosystems: Inland (mainly freshwater) Aquatic Ecosystems Marine Ecosystems Estuarine Ecosystems The inland aquatic ecosystems include lakes, rivers and streams that have negligible salin ity (salt cont ent) of a little greater than or equal to 10 gram of salt per 1 liter of water.
