“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

Definition of Wind Energy “Wind Energy - Energy received from the movement of the wind across the earth. This energy is a result of the heating of our oceans‚ earth‚ and atmosphere by the sun. Turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power.” The German physicist Albert Betz calculated in 1919 the possible maximum amount of energy that can be extracted out of wind energy. He came to the result of 59.3% that can be extracted and named this

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
