“The energy for life comes from the sun.” Outline the role of the photosynthesis process to explain what is meant by this statement. (3 marks) chlorophyll 6CO2(g) + 6H2O(l) + energy C6 H12 O6 (aq) + 6O2(g) 2830 kJ glucose Photosynthesis is the process in which plants use the sun’s light energy to convert carbon dioxide and water into carbohydrates such as glucose‚ sucrose‚ starch and cellulose. Carbohydrates are high energy compounds

Geothermal Energy Right now our country and planet as a whole‚ is in an energy crisis. Our non-renewable resources are running out. Oil is at outrageous prices and our economy is suffering. The people of this planet need to start looking for an alternative energy source because our fossil fuels will not last forever. Geothermal energy is one of many different ways we can preserve our fossil fuels. Geothermal energy is better for the environment because it does not involve burning and can not

An Argumentative Essay “Use of Nuclear Energy: Safe or Not?” 23 Aug Most countries today are becoming more and more dependent on nuclear power as a source of energy because of its high energy output and the availability of uranium used for fuelling nuclear reactors that generate power to provide electricity in households. Although using nuclear power as a source of energy has benefits like this‚ the danger posed by using nuclear power is very eminent. This was demonstrated in the recent Fukushima

to maintain “the backbone of any economy.” Thus‚ in our day to days living‚ we seem to ask ourselves about what is meant by the term "Nuclear Energy." Some will give the right concept of the nuclear energy but others will not. It all depends with the knowledge one has about the nuclear energy. In this research paper‚ I will write on how nuclear energy arise paying emphasis on the advantages and disadvantages and past cases in the nuclear arena. While nuclear power is much in the news right now

GLOBAL ENERGY CRISIS: THEN AND NOW Global Energy Crisis: Then and Now Introduction The world today faces an energy crisis. The world is dependent on certain natural resources like oil and natural gas that are quickly depleting. These resources are being imported from countries that have the ability to set higher prices due to demand (Nef 1977). Because of this‚ the world faces a great recession‚ and like Britain in the second half of the 16th century‚ we need to find alternative sources

renewable energy sources have long been debated‚ and examined but environmentalists such as Thomas Friedman believe that the use and production of sustainable energy resources is the way of the future and particularly vital to the advancement of the human race and the world‚ as we know it. As renewable energy sources such as solar power continue to become a more sought after approach for our everyday energy needs‚ engineers and environmentalists are developing innovative ideas for renewable energy and

augments in favor of the diversification of energy sources in Australia. Using alternative sources of energy of the dependency on fossil fuel such as coal may reduce the greenhouse gas emission impact on the environment. Nicholls (2009) speculates that using clean energy that depends on natural wind‚ sun and geothermal in not only practical and has economical advantages but it also may be able to reduce the CO2 emission to 50% by 2040. In addition‚ sustainable energy is not only essential for Australians

Hydraulics – CIVL 2130 Conservation of Energy Aim The aim of this lab experiment is to observe the flow behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies

McKenzie Smith Science 8-5 February 10‚ 2011 RSV Final Draft Energy Pathways This reading is about food chains‚ food webs‚ and food pyramids. The sun is the source of energy in a food chain. The energy from the sun can only be used by producers. The producers get eaten by consumers. A consumer is a herbivore‚ a carnivore‚ or an omnivore. Fungi and decay bacteria are decomposers. Decomposers break down and recycle dead things and make the soil better for producers. Food webs are the overlapping
