The Flow of Energy Stacey Ann Langston SCI/209 February 3‚ 2013 Cynthia Collin-Clausen The Flow of Energy The marine ecosystem relies on solar energy converted through photosynthesis by producers. Consumers‚ fish for example‚ metabolize‚ and release as chemical energy to convert into mechanical energy. The ecosystem distributes energy to living organisms through heat energy. Decomposers break down dead organisms and deplete them of their

“Investigate how light and darkness contribute to the cycling of carbon through both cellular respiration and photosynthesis of a plant” we devised a hypothesis that states‚ If we place the two test tube‚ one with carbonated water and the other regular water‚ with the Elodea inside a dark environment it will perform cellular respiration as it will not receive enough light energy to perform photosynthesis. From the result of our experiment we found that the test tube with tap water and Elodea changed from

The Solar System My project is about the Solar System. The Solar System is made up of all the planets that orbits the Sun. The Solar System consists of moon‚ comets‚ asteroids‚ minor planets‚ dust and gas. Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is the more gravity it has. The Sun is the star at the center of the Solar System. After the sun is Mercury‚ the innermost planet in the

Center: Hydrogen Basics U.S. Department of Energy Energy Efficiency and Renewable Energy Alternative Fuels Data Center Hydrogen Basics Hydrogen (H2 ) is a potentially emissionsfree alternative fuel that can be produced from domestic resources. Although not widely used today as a transportation fuel‚ government and industry research and development are working toward the goal of clean‚ economical‚ and safe hydrogen production and hydrogen fuel cell vehicles. Hydrogen is the simplest and most abundant element in the universe

Solar Panel The world’s energy demands increase year after year‚ while its resources are consistently being depleted in order to sustain these energy demands. These limited resources will one day be no more. A dependable source of renewable energy must be found. Currently solar energy is not efficient enough to sustain the population. However‚ the technology is constantly advancing‚ and solar energy could one day be that source. The solar cell’s roots can be traced all the way back

The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source

The purpose of the experiment is to determine the effects of sugar on photosynthesis in Elodea. Sugar water with Elodea‚ water with Elodea‚ and water (control) are used to test for photosynthesis. Five drops of sugar water were added to sugar water with Elodea beaker. The three beakers were left under normal light for photosynthesis to occur. After 60 minutes‚ NaOH solution was added to each beaker to test the volume of CO2. The result shows that both Sugar water with Elodea and water with Elodea

The respiration and photosynthesis cycle is the process by which plants and animals interact in a codependent and symbiotic manner to produce the nutrients‚ gases‚ and energy that they require to survive. Plants obtain energy from sunlight and use it to combine carbon dioxide and water into glucose and oxygen. This process is called photosynthesis. Animals eat plants containing glucose‚ and combine glucose and oxygen‚ releasing energy‚ water‚ and carbon dioxide. This process is called respiration
