“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

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

atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.

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

Review Energy Trading. 1) Other than price & quantity there are three common characteristics of any contract. Identify each of these three and discuss their relevance to valuation of commodities. Form: What exactly is being delivered‚ Cost of transformation: taking one form and transforming to another form. Riskless trade capturing the full cost of transformation. Space: Location for delivery of the contract‚ driver is the cost of transporting an asset from one point to another. Riskless

During exercise the body uses up large amounts of energy in three different ways. The ATP/CP system‚ anaerobic system and the Aerobic system all combine during periods of exercise to allow our bodies to continue exercise or playing sport. Most sports have a major system which takes up the bulk of the energy production during the activity and the timing in switching from one to another. This plays a major role in success in the playing arena. In a sport such as Australian Rules football it is important
