It is not only purely mechanical transfers of energy that follow this law of the conservation of energy, but all biological organisms must abide by this universal law as well. Take, for instance, the process of photosynthesis, which is considered the primary provider energy to almost all of life on Earth. Very simply put, "photosynthesis is the process of converting light energy to chemical energy and storing it in the chemical bonds of sugar" (Carter 1996). The process itself is actually quite complex, but basically several different pigments in plants (most essentially chlorophyll) absorb different wavelengths of light, which excites their electrons and causes chemical reactions to take place within specific molecules in the plant. These reactions ultimately result in the recombination of atoms into sugars, whose bonds can be broken to release energy when the plant needs it.
Plants are then eaten by other organisms, and te energy stored in the plant is converted yet again in the digestive process. One of the most basic processes for this conversion in many animals is the Krebs or citric acid cycle, which for animals is analogous to photosynthesis in plants (Kyrk 2008). The chemical process is again quite complex, but the principle of the conservation of energy remains the same. Glucose, the main sugar created by plants that is digestible for animals, is broken down, releasing the energy that the plants had stored in the sugar molecules during photosynthesis. Like any other reaction, some of the energy is lost to heat, but...
Energy and Its Sources Energy is an important element in daily life since it used for many activities like moving vehicles, promoting growth of the human body, and enabling humans to think. However, energy can be found in various forms like sound, heat, motion, and light though they are classified into kinetic and potential energy. While kinetic energy is the motion of substances, waves, objects, molecules, and atoms; potential energy is
3%, which is significantly less than what is being demanded. Solar energy that causes less pollution than coal-based energy is not used as often as we should because it cannot be created with as much ease as the latter source. In order to translate solar power into electricity, greater power generation prowess is to be utilized. This is what has led to decreased use of renewable sources. Everywhere we see, the

These massive walls of water travel faster than a commercial jet as they descend upon cities and islands. The energy and force of a Tsunamis is the massive transference of potential energy, caused by the shifting currents of the ocean, into kinetic energy that active pushes the Tsunamis forward. In 2004, one tsunami traveled 375 miles in a mere 75 minutes, about 300 miles per hour. Energy however is
energy and how it can be produced. Further it also delves on the various forms of energy and how energy can be conserved at home? What is energy? Energy is the vital and life sustaining force that is the source of the power that is used in the manufacturing of goods, the transportation of these goods, and the business involved in these two activities that form the backbone of the
The strategy is to partition the network and distribute the routing of the entire group of node instead of only one node having full energy burden task. Similar to the previous paper reviewed, Xu et al. (2000) in their paper titled "Adaptive Energy-Conserving Routing for Multihop Ad Hoc Networks" also develop two algorithms for routing energy saving devices. While other papers develop energy saving devices such as GAF and Span,
