Aquatic ecosystem

chemical and biological parameters of water and sediment as important for the aquaculture of marine shrimps. Along with dissolved oxygen, water temperature and salinity are considered as significant parameters because of their close association in aquatic ecosystem (OSPAR, 2005). The maximum water temperature recommended by Nunes et al., 2005 and ABBC, 2005 was 32°C, though the lower limit recommended by them varied slightly. Boyd (1990) suggests that 28-30°C is essential for the shrimp…

Convention of Biological Diversity (CBD)- Biodiversity is defined as the variability among living organisms from which all sources including inter alia, terrestrial, marine and other aquatic ecosystems and the complexes of which they are part; this includes diversity within species, between species and of ecosystems themselves. Floristic diversity refers to the variety and variability of plants in a region. Floristic structure is considered as one of the major exceptional characters of the…

or cloudy. (2008) The pH can be changed by some of the rocks in the water, such as limestone which neutralizes the acid in the water. (Oram, no date) “Nitrates are forms of nitrogen and is found in several different forms in terrestrial and aquatic ecosystems”. Nitrates in the water are caused by wastewater treatment plants, runoff from fertilized yards, and crop land. (EPA, 2009) Nitrates are found in proteins, and are always being recycled by plants and animals. “Bacteria in water quickly…

save natural resources and create a better world for all we must let go of the mentality that the world revolves around us as individuals, and focus on us as beings, like every other organism in the world, we are simply a small part of a greater ecosystem. This includes global resources, which we as a community deem irreplaceable, and in those cases must be preserved at all…

Solubility Phosphates are not very water-soluble, thereby creating a limiting potential for plant-growth in marine ecosystems. This explains its encompassing effect on the surface of affected water system, as observed in the Watershed Nature Centre. In addition, this can be observed from the site as less quantity of phosphorus get dissolved in running water compared to the amount that eventually gets into the water column. Temperature: The water surface gets heated up by sunlight, increasing…

-Short-Grass Prairie a. Overcrowding of species is a limiting factor because if there is an abundance of coyotes, it will lead to overhunting of smaller organisms b. Spreading of disease is a limiting factor because there is a dense population, so the diseases will spread faster c. Natural disasters is a limiting factor because there is an abundance of prairie fires that can reach the large population d. Human interaction is a limiting factor because things like dams affect the population of…

On a daily basis, I use an excessive amount of water. I am guilty of taking this resource for granted by taking long showers, not using a stopper while washing dishes, thus leaving the hot water running for far too long, and washing less than a full load of clothing on multiple occasions. Rather than wasting all of the water that I use in the shower and while cleaning dishes in the sink, I could have been reusing it as greywater. Greywater is household wastewater that can be reused to clean…

waste is able to infiltrate the river. Due to the suspension of particles in the river bacteria is prone to stick to these particles. With much suspension the plants on the riverbed will not grow as a result of no sunlight as well as upsetting the aquatic animal diversity by making it harder for predators to find prey. With a result of 3.73 we can say that there is no turbidity visible but there is a slight chance of infectious disease transmission as well as possible odour or taste of the…

Invasive species, also called nature’s invaders, are a species that is not native to the environment it now lives in and is harmful to the ecosystem of that environment. They can be there due to a natural phenomenon, such as a flood, but more likely they were brought there by humans. Therefore, humans play a huge role in creating and controlling invasive species. An invasive species is able to cause the extinction of the native plants and animals, they multiply quickly and take a lot of the…

DNA in Forensic Science Every organism contains cells within which an organic polymer called Deoxyribonucleic acid (DNA) is found. This particular polymer is composed of the phosphate backbone part, deoxyribose sugar part and also the nitrogenous base part. According to Butler, (2010), the phosphate backbone and deoxyribose sugar components are constant in all persons and, therefore, biologists today utilize the nitrogenous base component since it helps in distinguishing different individuals.…
