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
Non-living things in the desert are water, air, energy, substrate and chemical constituents, also known as nutrients. The non-living elements combined with the living organisms make up the desert ecosystem.Full Answer >
Living and nonliving things interact with each other by forming an ecosystem, where living things can obtain nutrients and energy from nonliving things through chemical processes. The nonliving things in an environment are known as abiotic factors, while living things are known as biotic factors.Full Answer >
Fungi are vital decomposers in the ecosystem, breaking down dead organisms and biological waste, freeing nutrients for use by other organisms and clearing away their remains. Fungi also act in partnership with some plants and algae, and are often vital to the survival of these organisms. Some species are parasites.Full Answer >
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 >
