Aquatic ecosystem

the chemical element flow between the living and nonliving components of the ecosystem. This is the cycle of nitrogen, phosphorus and carbon being converted into organic substances of plants and animals that are released back into the environment. There are three ways that human activities cause an imbalance of biogeochemical cycling on a daily basis. The carbon cycle (organisms in both terrestrial and aquatic ecosystems exchange carbon dioxide with the atomosphere) (essentials of biology,…

My determination to study aquatic and fishery science was started with the realization from my past, and it was my firm decision to walking through the right path. I was intrigued to study chemistry because I was astonished by vast and mysterious world of molecules in materials that…

Whereas adequate food intake leads to proper growth and augment the survival of a fish. However, survival, food intake and growth can be affected by the pollutants present in the aquatic ecosystem. With the increase in use of silver nanoparticles, it is more likely to disperse in water bodies via discharge from household, textile and food industries. Due to the nanosize (1 – 100 nm) it can easily penetrate the skin, tissues and organs…

100 worst invasive species worldwide (Boudjelas et al 2000.) They can survive and thrive in almost any freshwater ecosystem. They are able to outcompete other species of turtles for nutrients and territory and they threaten to decline the native turtle population wherever they live. A lot of pet turtle owners don’t know the threat red-eared sliders pose to their nearby ecosystem. The objective of this literature review is to examine and compile prior research about the effects that red-eared…

Acidic rain plays a key role in how rapidly things erode and die in our environment whether people notice it or not. Many are uneducated on this topic which makes it more dangerous to us and our surroundings. Not only can this toxic water effect trees and animals, but also buildings, statues, and even cars (webprojects.edu, 1). Acid rain is something humans should be concerned about in the twenty-first century due to our advancements in technology. The majority of the United States suffer from…

decomposers will also multiply, this could make aquatic animals suffocated and die because decomposers will need a lot of oxygen to grow. As the aquatic animals died the decomposers need to process them and that action needs oxygen again to proceed. A kind of organic pollution can occurs when the water contains inorganic materials like nitrogen and phosphates. This substances make aquatic plants and algae overgrowth, this also can kill the ecosystem inside the water because the plants need…

In the Florida Everglades ecosystem, Phosphorous is the main nutrient that the South Florida Water Management District is attempting to control. Phosphorous is the same nutrient that is a contributing factor to the algae problem in Lake Erie. In South Florida, the main source of drinking water stems from underground aquifers made of porous limestone, that is refilled via the everglades(NPS,2016). In our region, the main source for drinking water for cities, stems from Lake Erie. Thus,…

Introduction: Photosynthesis powers ecosystems and provides the Earth’s atmosphere with oxygen. It is a reaction that requires water, carbon dioxide and energy from the sun to produce glucose and oxygen. In the process of photosynthesis water is oxidised and carbon dioxide is reduced. The process of photosynthesis consists of two parts; a light-dependent reaction and a light-independent reaction. In the light dependent reaction the energy from light moves the electrons from a photosystem…

organisms. Secondly, I will be examining my personal involvement in the nitrogen cycle and the impact those actions have. Then, I will be looking at ways that my actions can be altered to benefit the environment and reduce my negative impact on the ecosystem. Finally, I will attempt to answer the question of, how difficult it is to balance my personal life choices with the needs of the environment? Nitrogen is an essential element in living things, it is directly involved in the formulation…
