Ecosystems Components SCI/256 A region that receives fewer than 10 inches of rain annually is considered a desert. This lack of precipitation loosely illustrates what encompasses the desert ecosystem. Although there are many cold deserts around the globe‚ for the purpose of analysis‚ the focus of this paper will be hot desert ecosystems. The extreme heat of the day in some deserts can reach above 120 degrees and drop down below 32 degrees (National Geographic‚ 1996-2013). These temperature extremes

Soil is an important natural resource that covers much of the earth’s land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay‚ which helps return nutrients to the soil. In addition‚ many kinds of animals find shelter in the soil. Soil contains mineral

Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

Marine Ecosystems are the largest systems on the planet‚ covering over 70 percent of the Earth’s surface and constituting over 99 percent of the living space on the planet (area x depth). These vast ecosystems are composed of many different habitats which extend from the near shore regions to continental shelves and the deep ocean. They are home to millions of species and provide food‚ income‚ protection‚ and many other vital ecosystem services to billions of people around the world. ECOLOGICAL

In ecology‚ the competitive exclusion principle‚ sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law‚ is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other‚ leading to either the extinction

Soil erosion is a major concern in the southeastern region of Nigeria due to high population densities and farming techniques‚ which has resulted in the presence of numerous gullies. While gullies are found all around the world‚ the existence of gullies in Nigeria is regarded as one of the worst environment disasters‚ having negative implications on the environment and the quality of life for humans and other species (Adetona & Ezezika‚ 2011; Ajaegwu & al‚ 2010). Large quantities of soil in Nigeria
