Energy Flow Robert Green 1/9/15 SCI/275 Christina Kamnikar Energy Flow After reviewing figure 4-10 presented in chapter 4 of Environmental Science‚ it is easy to recognize the different trophic levels. Each trophic level shows how energy and biomass flow through a food chain however it is eventually lost as heat. These levels consist of: biomass of producers‚ those consumed‚ and those not consumed. The first trophic level has the producers which graze the food chain‚ grazers consist of the

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic
