Write An Essay On The Carbon Cycle

Nowadays, as a part of the human activities, CO2 is produced in large amounts due to the industrial activities. There are four main sources responsible for the production of carbon dioxide into the atmosphere: combustion of fossil fuels, transportation and industry. The first source of emission of CO2 is burning of petroleum and fossil fuels. During the process of combustion of fossil fuels, Carbon reacts with the oxygen resulting in the production of Carbon Dioxide. For example, in order to generate electricity, fossil fuels are burned.

Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs use sunlight to make food, the process is called photosynthesis. Plants, algae, and some bacteria can use photosynthesis. The reactants of photosynthesis are carbon dioxide and water, captures energy into chemical bonds. The products are sugar and oxygen.

The relationship between Photosynthesis and Cellular Respiration is that the reactants on photosynthesis are the products to cellular respiration, and the products of photosynthesis are the reactant. Photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts it back into the atmosphere. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food. Cellular respiration and photosynthesis differ because they occur in different places and they do different things. Cellular respiration is the breakdown of glucose to release stored energy for a cell to use.

It involves carbon dioxide added to water added to sun energy then is yielded to sugar and water. Photosynthesis is also the location of pigment reaction, meaning it’s where the molecules are usually located. Similar to cellular respiration, plants get their energy through photosynthesis. This is a process which happens when the sun (and certain types of lights) is present. Taking place within plants and some bacteria, more specifically the chloroplasts.

This experiment is set up the study the effect of different sodium bicarbonate concentrations on the rate of photosynthesis in spinach (Spinacia oleracea). Photosynthesis is the process by which plants and other photoautotrophs synthesize organic compounds from carbon dioxide (Faculty of Science and Horticulture, 2018). Photosynthesis takes place in the chloroplast of a plant cell, where sunlight, water, and carbon dioxide are used in a reaction to produce oxygen and sugar (Reese 2017). In the photosynthesis reaction carbon dioxide is reduced to make sugar and water is oxidized to make oxygen. In this experiment oxygen production is being used to measure the rate of photosynthesis.

Two way to produce activated carbon are physical and chemical activation. In physical activation, under passive atmosphere the material is carbonized, and as the activating reagent Use carbon dioxide or steam.while in chemical activation, different chemicals are used to help with the initial dehydration. (Toles et al., 2000) Activated carbon adsorption

He began studying the properties of CO2 in the 1750’s and found that calcium carbonate could either be heated or treated with acids to produce a gas he called "fixed air." He noted that the fixed air was denser than air and didn’t support flame or animal life. He used this finding to show that carbon dioxide is produced by animal respiration and microbial fermentation (Anderson, 2013). The uncovering of carbon dioxide is so critical because it is vital to all life on earth. Plants and animals are connected to each other through the carbon dioxide and oxygen cycle.

The beginning of the cycle started with the amalgamation of CO2 into organic molecules. This process; carbon fixation involves the reduction including electrons delivered by NADPH. Since "ATP from the light reactions influences parts of the Calvin cycle, it is the Calvin cycle that creates sugar, with the aid of ATP and NADPH from the light reaction". The raw materials for anabolic pathways and fuel for respiration is provided when Carbohydrates takes form of disaccharide sucrose travel through the veins to non-photosynthetic cells, and formation of the extracellular polysaccharide cellulose. Cellulose is the utmost plentiful organic molecule, as well as the main ingredient of cell walls in plants.

Most terrestrial organisms require oxygen to survive and much of the oxygen in the atmosphere is produced by photosynthesis. Plants are the organisms that carry out this chemical reaction and so it is crucial to understand what impacts this process in both terrestrial and aquatic environments.

These cells can swell up to open the stomata or deflate to close them off (berkley) This is important because any time stomata are open the plant will lose water along with oxygen (berkley) When enough carbon dioxide has entered the stomata, a plant will close its stomata so it can preserve its water and prevent itself from drying out. Environmental conditions can alter stomata density (Tansley reviews). In many species, stomata density is reduced with increases in atmospheric carbon dioxide levels in geological time and under laboratory conditions (tansley reviews). In a study of 100 different plant species, it was found that three quarters of the species analysed showed reduction in stomatal density (Tansley reviews). This would be an advantage for the plant as fewer stomata are better able to conserve water than its original
