Trees are one of the most important aspects of the planet we live in. Trees are vitally important to the environment‚ animals‚ and of course for us humans. They are important for the climate of the Earth‚ they act as filters of carbon dioxide‚ they are habitats and shelters to millions of species‚ and they are also important for their aesthetic appeal. However‚ the trees on our planet are being depleted at a very fast rate. According to some estimates‚ more than 50 percent of the tree cover has disappeared

Respiratory System Mechanics E X E R C I S E NAME: Ailyn Sedaria-Lapuz LAB TIME/DATE: March 3‚ 2013 1. Define each of the following terms: • respiration : means exchange of gases ( oxygen and carbon dioxide) between a living organism and its environment; Breathing. • ventilation: movement of air in and out of the lungs • alveoli: small air sacs or cavities in the lung that give the tissue a honey comb appearance and expand its surface area for the exchange of oxygen. • diaphragm:

produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen at a slower rate because gradually there will not be enough sunlight as there is carbon dioxide and water. APPARATUS: lamp x 1 beaker x 1 (1L) test tube x1(up to the top) water 500ml(up to

there are several greenhouse gases that were responsible for warming and human emit them in a variety of ways. These gases include water vapor‚ nitrogen‚ methane and carbon dioxide. Most of these gases come from combustion of fossil fuels in cars‚ factories and electricity production. The gas responsible for most warming is carbon dioxide. Other contributors include methane from landfills and agriculture

Deforestation - Wikipedia‚ the free encyclopedia Deforestation From Wikipedia‚ the free encyclopedia Article Talk Read View source View history Search For other uses‚ see Deforestation (disambiguation). Deforestation‚ clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use.[1] Examples of deforestation include conversion of forestland to farms‚ ranches‚ or urban use. More than half of the animal and plant species

They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. The equation for photosynthesis: Carbon Dioxide + Water (+ Light Energy) → Glucose + Oxygen Symbol equation: 6CO2 + 6H2O ------> C6H12O6 + 6O2 (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/plants/plants1.shtml) The effect of the concentration of carbon dioxide on the rate of photosynthesis:

CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis At the same

individuals and comply with the desires from government officials mainly in the United States but also in other countries. Global warming is the theory that the Earth is constantly heating up above normal levels due to elevated amounts of CO2 (Carbon Dioxide) in the atmosphere‚ which deteriorates the ozone and corrupts the greenhouse effect which maintains normal conditions of life (Courtney). Worldwide‚ global warming is happening‚ and most of the reason this is happening is because of manmade activities
