the carbon cycle essay

our biology book, “there are several elements (water, oxygen, carbon, nitrogen, phosphorus) that cycle through our world just like energy is cycled. These elements are never created or destroyed, but instead they are constantly recycled and reused.” Various human activities can hamper/benefit these cycles. Two of the cycles and how they are benefited and adversely affected by human activities are explained below. The hydrological cycle is where water is stored in places like oceans and ponds, and

from the outer side and brings it into the lungs and there it is diffused through the lungs into the blood stream. The circulatory system carries the oxygenated blood throughout the body in where the oxygen is exchanged for waste materials and the carbon dioxide is carried back to the lungs and let out of the atmosphere to exchange for the oxygen. The digestive system interrelates with the respiratory system because, the respiratory gives oxygen to the digestive system. The digestive system interrelates

in cellular respiration. In photosynthesis, cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun, and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2 In cellular respiration, glucose and oxygen are taken into the cells, then they are converted to carbon dioxide, water and ATP energy and some other energy. Some of the

within the presence of oxygen. All living cells must carry out the process of cellular respiration. Cellular respiration is pivotal for cells because it makes the energy that is used in photosynthesis. Through changes within glycolysis, the Krebs cycle and the electron transport chain, one is able to analyze how cellular respiration works, as well as gain an understanding of why it's important to the life of a cell. There are three main steps to cellular respiration. The first step is glycolysis

from the sun. Photosynthesis creates oxygen and organic molecules that are used by the mitochondria of eukaryotes as fuel for cellular respiration. Respiration then breaks down the fuel generating ATP. The waste products of this type of respiration, carbon dioxide and water, are the raw materials for photosynthesis. Photosynthesis is the process where chloroplast in plants and other photosynthetic organisms capture light energy and converts it to chemical energy that is stored in sugar and other organic

average, the climate scenario RCP2.6 resulted in the highest values for NPV, size diversity and total carbon stock under all management intensities, and the highest species diversity under most intensities. In year 2100, in general, the 20-year cutting cycle led to higher total carbon stock and size diversity but lower NPV and species diversity. Low-intensity management caused the highest total carbon stock (10 years: 823 – 854 ton ha-1; 20 years: 864 – 888 ton ha-1) and size diversity (10 years: 1

the mitochondria, when this is happening the pyruvate molecules are converted into 2-carbon molecules these molecules then enter the Kreb Cycle. Moving on the energy created will now enter the electron transport chain, this energy will then produce ATP. The reactants are glucose and oxygen and the products are ATP, water, and carbon dioxide. During the Cellular Respiration glucose is being oxidized, along with carbon. On the other hand Oxygen, NAD+ and FADH are being reduced in Cellular Respiration

The carbon cycle is also a very important part of the ecosystem. The carbon cycle is how the carbon gets transferred from the lithosphere, atmosphere, hydrosphere, and biosphere. The carbon cycle starts with plants using the CO2 in photosynthesis. During photosynthesis plants use water, energy from the sun and carbon to make a compound called glucose as well as releasing oxygen. Then as the plants get eaten by consumers the glucose (which includes carbon) moves up the food chain
