The four cycles important to ecosystem are water, carbon, nitrogen, and phosphorous. The Water cycle describes the movement of water on Earth through evaporation, transpiration, condensation and precipitation. Carbon cycle is crucial for all organic living organisms. Carbon is produced by combustion of wood and burning of fossil fuels, which plants then take in; animals eat plants and exhale carbon dioxide, which is one-way carbon, is placed in the atmosphere. An additional source of carbon is the ocean floor absorbs carbon sediments and when they move a volcanic eruption occurs and releases carbon dioxide gas during an eruption as well as decomposition of plant and animals, which return carbon to sediments. After millions of years, these sediments create fossil fuel or oil which when burnt returns carbon to the atmosphere. Carbon is truly a co-dependent cycle. Photosynthesis removes carbon from the atmosphere and exhaling returns it to the atmosphere. Nitrogen cycle is a natural process where nitrogen passes through air to soil to organisms through a process of nitrogen fixation and denitrification. Nitrogen is important, as it is useful in the production of amino acids, protein, and nucleic acids. It is the most abundant. Phosphate is essential to cell membranes, human bones, teeth, and plant life. Phosphorous is minimally in the atmosphere as dust particles .Plants absorb phosphate thru the soil animals eat the plants and via decomposition or waste phosphate is…
