Abstract

Humans impact to the carbon cycle with the circulation of the carbon among many living organisms and their environment as well. The carbon dioxide that is surrounded will be synthesized by the plants and their tissue that is swallowed by animals with transforming in to carbon dioxide again while living or dead. The humans affect this cycle with taking 40% from the photosynthetic effect of plants on land. Where there are burning fossil fuels that has an increase the carbon dioxide to 35%. When combustion occurs by the surrounding of oxygen, carbon dioxide and water molecules are set free in the atmosphere. The phosphorous cycle is the element that is in rock and soil minerals which when the rocks starts to break down the phosphorous is released. …show more content…
Humans have contributed to phosphorous entering the oceans and increase the phosphorous cycle to go faster. Once the phosphorous leaves the soil it will not return and causes pollution in the ocean killing animals in the ocean. The nitrogen cycle occurs there are bacteria in the soils, water and sediments. Nitrogen is a must have a requirement for water and land plants. Humans are important contributors to the nitrogen cycle. Not only do humans increase the nitrogen rate but also in crops that are grown and nitrogen is in more of the non-leguminous crops. In an opinion it is hard in some cases for humans depend on transportation and this is one of the ways they contribute to

    Will Restricting U.S. Carbon Emissions Damage the U.S. Economy? Essay Example

    Carbon is an element essential to all living things on Earth. It undergoes two cycles that are necessary to stabilize the environment: the biological carbon cycle and the geological carbon cycle. In the biological carbon cycle, carbon is absorbed in plants and the inorganic carbon is converted to its biological form through photosynthesis via plants and phytoplankton ("Carbon cycle," 2008). During respiration, carbon dioxide reenters the air after being broken down for energy (ATP) carbon dioxide gas. Carbon that remains in the oceans sink are buried into the earth's crust. When humans extract oil and coal for energy usage the byproduct carbon dioxide is released affecting the geological carbon cycle. The biological cycle is affected in two ways. When forests are cleared for land usage, the burning causes a release in carbon dioxide and the cleared land can no longer assist in the process of photosynthesis or the removal of carbon dioxide from the atmosphere ("Carbon cycle," 2008).…

    Since the beginning of time humans have affected the biochemical cycles in many different ecosystems. Some of the impacts made have been within the carbon, nitrogen, and phosphorus cycle. The Mohave Desert is affected by the carbon cycles when people are driving at 70mphs and they surprise a helpless animal which might be trying to cross the highway, and then get shit by the car. The poor animal is now lying dead on the side of the road, and this will release a large quantity of carbon dioxide that will eventually ties up the biological tissues which are released again into the atmosphere. One other way that…

    U High Creek Water Quality

    Runoff is a problem when farmers use too much nitrogen on their crops to help them grow and the excess nitrogen flows into creek and other bodies of water when it rains. This excess nitrogen causes more algae to grow in an algae bloom, which causes the bacteria that eats this algae to multiply as well and use up all the oxygen in the ecosystem. This leaves other organisms to die in the process called eutrophication. Another way that humans can affect a water ecosystem is by littering near or even far away from a body of water. Wind, runoff, and other conditions can carry the rubbish, such as plastic bags, bottles, and paper, into the creek which decomposes over time and leaves harmful chemicals and gases. These dangerous pollutants can decrease the water quality and cause organisms to die (Umgeni Water Amanzi). Overall, humans can impact water ecosystems in a lot of…

    Relationship Between Photosynthesis And Cellular Respiration

    The carbon cycle is a biogeochemical cycle that displays how carbon circulates throughout the environment. Many components affect this process such as photosynthesis and cellular respiration. Photosynthesis uses the carbon dioxide that is in the atmosphere to transform it into sugar and oxygen; cellular respiration puts carbon dioxide in the air. Both of these processes were studied during the experiment. In the experiment, the tube with both the elodea and the snail had the same level of carbon dioxide in both the light and dark tube. This occurred because the snail performed cellular respiration, and the elodea performed both photosynthesis and cellular respiration. In the light, the solution was a yellow green, and in the dark, the solution was a yellow green. From this experiment, there is some carbon dioxide present when an organism that performs both cellular respiration and photosynthesis and another organism that performs only cellular respiration are paired together.…

    Cycles in Biology

    Carbon is an essential component of all organic substances, necessary in nucleic acids, proteins, carbohydrates. The only way that can enter ecosystems is when it’s used for photosynthesis. Carbon dioxide diffuses into the plants stomata and through the Calvin cycle is combined with other molecules to make glucose. This may then be used in lipids, carbohydrates and proteins, incorporating carbon into the plants biomass e.g. cellulose cell wall and used for respiration. When a plant respires it releases some of this carbon back into the atmosphere as carbon dioxide. Moreover if deforestation or slash and burn occurs it releases carbon dioxide into the atmosphere during the combustion process. When the primary producer is eaten by the primary consumer it passes its biomass and carbon along too. This happens through all the trophic levels. The consumers will leave detritus either urine, faeces or the carcass, or in the case of producers leaf litter. Decomposers known as Saprophytic bacteria then break down the detritus using enzymes. As they do so they respire again releasing carbon dioxide into the atmosphere. If plants or animals die in situations were there are no decomposers for instance deep oceans, the carbon in them may turn into fossil fuels over millions of years by the process of fossilisation. Alternatively vast amount of the carbon is used by marine zooplankton to make calcium carbonate shells. These are not…

    Cycles in Biology

    One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric composition currently consists of approximately 0.04% of Carbon dioxide. A large proportion of it is found dissolved in the oceans as well as the atmosphere. The carbon cycle consists of 6 stages. Initially the CO2 that is absorbed by plants for the use in photosynthesis becomes carbon compounds in plant tissue. The carbon is moved up the food chain by consumption, a primary consumer. It is passed on to the secondary and tertiary consumers when they eat other consumers. When these organisms die they are digested by microorganisms known as decomposers (bacteria and fungi), when these decomposers feed on the dead organism it is called saprobiotic nutrition. The carbon is then released back into the atmosphere and other living organisms which proceed on to respiring and this causes CO2 to be released. However if the dead organism ends up somewhere were there is no decomposers present, then this matter will turn into fossil fuels over millions of years. We will then extract the fossil fuels and use them for energy and as fuels, this process known as combustion is very widely used, it then releases CO2 back into the atmosphere where it once came from.…

    Carbon Cycling

    Carbon is the fourth most abundant element found on Earth, and is essential to all life as we know it. It is found in all living substances, and is essentially the key element for life. Because the carbon atom has the ability to form bonds with up to four other atoms, it can help form solid minerals (such “ limestone), ‘squishy’ organisms (such as plants and animals), and it can be dissolved in water. Carbon is also present in rocks, dissolved in rivers, lakes and oceans, and is in the atmosphere as carbon dioxide. The exchange of carbon between these reservoirs is identified as the ‘carbon cycle’. The paths taken by carbon atoms in this cycle are known as ‘sinks’, and are extremely complex, as they may take millions of years to come full circle. In this essay I will demonstrate understanding on how carbon is added to, and removed from, the atmosphere and how it is stored. I will explore the main processes in the carbon cycle – photosynthesis, respiration, plants, animals, decomposition, oceans, fossil fuels, and volcanism – and how they interlink together to form a complete and full cycle.…

    1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants, for starters, are a major part of this carbon cycle. During photosynthesis, plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain homeostasis. Unlike photosynthesis, carbon is the waste product in respiration, while oxygen is removed from the atmosphere. If carbon isn’t cycling through either photosynthesis or respiration, it reacts with water, in the form of carbon dioxide, to produce bicarbonate. The bicarbonate is a source of energy for aquatic producers such as algae and other aquatic vegetation. On similar terms to the formation of bicarbonate, when aquatic organisms respire, the carbon dioxide released from them in turn reacts with water to form bicarbonate. Human activity has also made a huge impact in this cycle. As humans continue to use fossil fuels daily, the amount of carbon dioxide in the air increases. Lastly, one must remember that the amount of bicarbonate in the water is in equilibrium with the amount of carbon dioxide in the air in the carbon cycle.…
