Reproductive Biochemical Cycles

Superior Essays
The earth is reliant on various reproductive biochemical cycles, to maintain balanced and regulated conditions on earth and within the atmosphere (Name, date). These cycles include the carbon, nitrogen and hydrological cycles. These cycles among others, bring with them various geological, chemical, physical and biological processes (name, date). All these cycles are interconnected; matter within them is continually cycled between biotic and abiotic parts of the environment (name, date). Without appropriate nutrient and element cycling on earth, ecosystems would become unsustainable as these cycles firstly ensure that there is no waste, whilst also ensuring essential elements do not run out as they are continually recycled (name, date).

Often referred to as the ‘building blocks of life’ the carbon cycle is the circulation and transformation of carbon between living organisms and the environment, as many living tissues contain carbon compounds (name, date). One of the most common elements on earth, carbon is the basis for all living things and the environment; carbon takes many forms and is distributed through the carbon cycle (name, date). Carbon exists in three main forms these include solid (coal / diamonds) liquid (crude oil) and as gas (carbon dioxide) making it widely distributed (name, date). The carbon cycle is separated into two main cycles, this includes the long term carbon cycle (also known as the geological cycle), which described the movement of carbon between surface reservoirs including rocks, minerals the ocean and the atmosphere (name, date). The second cycle is the short term cycle (also known as the biological cycle) which explains the movement of carbon between vegetation, living organisms such as animals,soil and fossil fuel burning (name, date). Both of these cycles make up the global carbon cycle, the long term cycle can be slow in the movement of carbon whereas the short term is more rapid (name, date). The phases of the carbon cycle act as a long term global thermostat, providing a hospitable environment for organisms to …show more content…
Melting is a stage but only in select environments (name,date). Water in the oceans moves to the atmosphere through evaporation, when heated by UV rays. This is where liquid water is turned into vapor or gas. Once this is in the atmosphere, atmospheric circulation transports it around the word. As this water is carried over land is is released in the form of precipitation either as rain or snow (when clouds can no longer withstand the weight of the snow or rain it is released). This may stay on land in the form of snow for years at a time but can also stay on land for allot longer as ice in solid form, this eventually melts and enters the cycle via transportation (name, date). Water can be transported across land in rivers, streams before being evaporated back into the atmosphere. Water can be stored in reservoirs such as lakes, absorbed into soil and rocks or may become groundwater (water that flows underground towards the nearest ocean)(name, date), it may continue to flow underground as run off until it reaches the ocean again. Plants release water into the atmosphere all the time through a process known as transpiration, during photosynthesis water release is higher. When plants absorb water through their roots, water vapor is released in the pores in their leaves in exchange for the intake of co2. This

    It has the biggest amount of carbon on the planet. Terrestrial ecosystems such as plants, animals, soil, and microorganisms are all the organic compounds that ingest, create, and store carbon. From the atmosphere, plants use photosynthesis to create energy, which also becomes an energy source for animals that eat the plants. When those animals die, their bodies decay into the soil, which is how carbon is stored into the soil for many years. Deep-water formation can mix the soil and the deep ocean to create carbon flow4.…

    All the organic compounds have carbon as the basic component. It is present in food materials as carbohydrates, proteins, fats and amino acids. The basic movement of carbon is from atmospheric reservoir to producers, to consumers and from both these groups to decomposers and then back to atmosphere. The main source of all carbon found in living organisms is carbon dioxide and dissolved carbon dioxide in water. In atmosphere the concentration of carbon dioxide should be 0.03-0.04% in natural way but due to industries and other sources this percentage is increasing.…

    Carbon Cycling Internal Achievement Standard Science 90953: Demonstrate understanding of carbon cycling Carbon Cycling Internal What is the Carbon Cycle? Carbon is a key component in all living organisms and can be found in both living and nonliving organisms. Organisms will continue to contain carbon even when they change or decay. Carbon is found in a variety of living things and can exist as a solid e.g coal and diamonds, a liquid e.g crude oil or a gas, for example CO2 (carbon dioxide). Often, carbon is referred to as the “building blocks of life” as living things are based on carbon or carbon dioxide.…

    It is the building block of life, as all organic organisms are composed of carbon based compounds. Carbon is abundantly found in the atmosphere in a active pool in the form of gaseous Co2. Atmospheric Co2 is released from the storage pool through the physical processes of combustion of organic material and decomposer respiration. Co2 returns to the storage pool through the process of photosynthesis, via the Calvin-Benson reaction. bi) Co2 gas cycles through the environment in a number of different ways.…

    It also shows that while plants release oxygen through photosynthesis, they also need it for respiration and hence oxygen is consumed while also being produced. They use the oxygen for aerobic respiration, a catabolic reaction, which uses glucose and oxygen to form carbon dioxide and water and releases…

    Rain occurs when condensed moisture in the atmosphere falls to the ground in separate, visible drops and it provides us with another source of water and can be used to provide plants with water such as in rainforests or countryside. The hydrologic cycle allows for rain to form and pour down in different areas. Water from oceans, swamps, lakes, rivers are evaporated and turn into water vapor due to the water being heated by the sun or other means. This water vapor rises into the troposphere (where most weather phenomena occur) and cools as it ascends. When it condenses, the water vapor become water droplets that form clouds.…
