To determine how sustainable the carbon sink is, we have to know how much carbon is used in terms of printing paper (carbon footprint of printing paper). ... There is 8.4 g of carbon stored in each sheet of paper (Upstream Solutions), therefore: (8.4g*8,730,607 pieces of paper)/1000 = 73337.0988 kg of carbon. ... To sustain the amount of carbon used in printing paper, the carbon sink should store at least this amount of carbon. As mentioned before, the carbon sink currently stores 13874.59033 kg of carbon, which is 5.29 times less than what is needed to sustain our usage of photocopying pape...

The role of plants in their natural environment is to absorb excess carbon dioxide and produce oxygen to replace the CO2 in the air. Carbon dioxide is harmful because it is toxic and because it is one of the gases that causes the greenhouse effect. ... Photosynthesis and cellular respiration both involve the absorption of gases and the release of a by-product, but photosynthesis involves the absorption of carbon dioxide and water and the release of organic compounds and oxygen, while respiration is exactly the opposite. ...

Earthworms Earthworms are part of the phylum: Annelida. There are other things also included in this phylum such as bristle worms and leaches. They are bilateral, which means that if you cut them down the middle long ways they would be the same on both sides. Earthworms live in most any habitats e...

Global warming increases the amount of carbon dioxide in our air. While that is good news for plants since they breathe in carbon dioxide, it's bad news for our children who are being deprived of oxygen. ... Global warming is going to continue to cause problems in the world for centuries to come in increased carbon dioxide and pollen levels to name just two issues. ...

The immense amounts of sulphur dioxide emitted into the air causes high levels of acid in the atmosphere. ... As with sulphur dioxide in rain, mercury is also discharged into the water. ... An inordinate amount of sulphur dioxide is let into the air, more than can be neutralized by nutrients in the air. ... Acid in the soil in causing the carbon dioxide respiration process to decelerate. In order for plants to go through photosynthesis, they need carbon dioxide. ...

Introduction: Photosynthesis is the process in which green plants utilize the energy of sunlight to manufacture carbohydrates from carbon dioxide and water in the presence of chlorophyll. ... Through photosynthesis, plants give off oxygen for us to breathe, and we supply plants with carbon dioxide need for the process of photosynthesis....

The biogeochemical cycle for carbon starts with the carbon dioxide (CO2) in the air and bicarbonate (HCO3) in the water. Through photosynthesis and metabolism the carbon atoms from CO2 becomes the carbon atoms of the organic molecules that make up the plant body. The carbon atoms then move into the food webs and become part of the tissues of all organisms in the ecosystem. ... Nitrogen has the unique properties of both carbon and phosphorus. ... In the case of carbon, the rate increases due to the cutting or burning of the forest. ...

Introduction: The purpose of this experiment was to compare how the rate of photosynthesis varies depending on light intensity. By definition photosynthesis is a process that converts light energy into chemical energy that are stored in the bonds of a carbohydrate. The main item photosynthesis nee...

Te easiest way to define photosynthesis is the process by which plants use carbon dioxide (CO2) and water and turn it into oxygen. ... To turn the water acidic, carbon dioxide (CO2) was blown into the test tube via a straw. ... Carbon dioxide was added to each test tube by blowing into them through a straw. ...

Photosynthesis can be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. ... Moreover, if we look at the results table and at the graph, we can see that from trials 4-6 there was a higher amount of oxygen produced (4 mm3 ) than from trials 7-10, (2-3 mm3) we might had expected that at these higher light intensities (from trial 7-10) more oxygen was going to be produced, however, this was not the case because as I mentioned in the prediction, as light intensity increases, the photosynthetic rate is being limited by certain factors...
