Eutrophication is the process of enriching an ecosystem with nutrients, primarily nitrogen and phosphorous. It can occur naturally in aging lakes. Humans can also introduce these nutrients into an ecosystem, at which point it is called artificial eutrophication.
Fertilizers used in farming can be washed into nearby water bodies, enhancing their nutrient levels. Eutrophication leads to extensive growth and reproduction of algae in the form of algal blooms. These can both benefit and, from time to time, harm the ecosystem. The goal of all eutrophication, natural and artificial, is a balanced and healthy nutrient level in a lake or other ecosystem.Learn More
The water cycle, also known as the hydrologic cycle, describes the process of how water moves through Earth's environment. In general, water evaporates from oceans, then it condenses in the atmosphere as water vapor cools. When enough water gathers in clouds, it precipitates back to the Earth's surface as rain, hail, snow or sleet.Full Answer >
Collection refers to the process by which water gathers back into bodies of water such as rivers, lakes and oceans. This begins with precipitation, when water falls from the clouds in the form of rain, snow, sleet or hail. A lot of the time, precipitation falls directly into a body of water, but at other times, it soaks into the ground, where plants, people and animals end up drinking it as ground water. Most of the water will end up leaching back into bodies of water through the soil.Full Answer >
Assimilation in the digestive system is the process by which nutrients from foods are taken into the cells of the body after the food has been digested and absorbed, according to IvyRose Holistic. There are four basic stages of the digestive system process.Full Answer >
To prevent eutrophication, people must use cleaning agents and detergents that are biodegradable and that do not contain phosphates. To further reduce the amount of nutrients that are causing an overgrowth of algae in lakes and streams, laws need to be created that regulate the dumping of waste water.Full Answer >
