Cycles of Elements required for life
Carbon cycle
All living things are made of carbon. It is also part of the ocean, rocks and even air. Earth is a dynamic place so the carbon does not stay. It is moving in the atmosphere where the carbon is attached to some oxygen in a gas called carbon dioxide. We all know that plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and buried will turn into fossil fuels made of carbon dioxide like oil and coal over millions of years and when humans burn the fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide. Carbon dioxide is consider a greenhouse gas and traps the heat in the atmosphere. Without …show more content…
It makes up about 65% of the mass of the human body and you can identify that it is the most common element of the human body. Most of this is in the water form. However, the Earth is also 30% oxygen and the atmosphere is 20% oxygen. Oxygen is being used and created through the different processes on these planet. All of these processes together makes up the oxygen cycle. The carbon cycle is connected with the oxygen cycle. In the example of the oxygen cycle shown in the left hand side, you can see how oxygen is used by plants and animals. Plants are the main creator of the oxygen through the process of photosynthesis. As you can see in the picture the plant uses the sunlight and carbon dioxide to produce and release oxygen. The sheep breathes in the oxygen and then breathes out carbon dioxide which the plant needed for the process called photosynthesis and the oxygen cycle is …show more content…
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple forms as it goes by among the atmosphere, terrestrial, and marine ecosystems. These cycle can occur throughout the biological and physical processes. The five main processes of the nitrogen cycle through the biosphere, atmosphere, and geosphere includes the nitrogen fixation, assimilation, nitrification, ammonification, and denitrification. Many of those processes are carried out by a microbes, either in their effort on harvesting energy or to accumulate nitrogen in a form needed to their growth. The Earth’s atmosphere is consists of 78% nitrogen. The nitrogen cycle is one of the particular interest of the ecologists because nitrogen availability can affect the rate of the ecosystem processes, including primary production and decomposition. Human activities such as burning of fossil fuels, use of artificial nitrogen fertilizers, and release of nitrogen in wastewater have dramatically affected the global nitrogen cycle. Just like Oxygen, Nitrogen is also an important element to all life on Earth because nitrogen is an essential component of DNA, RNA, and the building blocks of life. All organisms require nitrogen to live and
