Energy transfer

Energy transfer is the transfer of energy from one body to another.

There are a few main ways that energy transfer occurs:

food pyramid

food pyramid or Food Guide Pyramid, diagram used in nutrition education that fits food groups into a triangle and notes that, for a healthful diet, those at the base should be eaten more frequently than those at the top. At the base of the pyramid are breads, cereals, rice, and pasta, with a recommendation that 6 to 11 servings be eaten daily. On the next levels up are the vegetable (3 to 5 servings) and fruit (2 to 4 servings) groups, followed by the dairy group (2 to 3 servings) and a group including meats, eggs, nuts, and dry beans (2 to 3 servings). Fats, oils and sweets are at the apex, with a recommendation that they be eaten sparingly. The Food Guide Pyramid was adopted by the U.S. Agriculture Department in 1992 as a replacement for the "four food groups" scheme that had been used to teach children about nutrition since the 1950s. The four food groups (the milk group, the meat group, the bread and cereals group, and the vegetable and fruit group) had put a greater emphasis on the consumption of meat and dairy products. The adoption of the food pyramid design was delayed by debate between nutritionists (who felt that it was an effective teaching tool that demonstrated current thinking about the benefits of a low-fat, high-complex carbohydrate diet) and the meat and dairy industries (which felt that the positioning of their products among the foods to be consumed less frequently implied that those foods were unhealthful).

Question:Im a freshman in high school and our mid terms are coming up in about three days. My bio teacher gave us the questions to the exam but there are a few questions i dont understand. 1. "using a energy pyramid with trophic levels explain what happens to the energy within the pyramid" 2. "Draw a diagram of an energy pyramid with at least 4 trophic levels and label each level" 3" explain fully the carbon cycle using all correct termonology" 4. " Explain how latitude changes and elevation changes can demonstrate similar climate changes. Note: Remember the 3 factors that most influence climate" 5. "what is metabolism, what are two types of metabolism and explain each type" Please Help!!

Answers:1. http://www.stevetrash.com/lessons/lesart/epyramid.gif Most biomass is on the bottom. When mouse eats 10 grams of grass, it only gets heavier by 1 gram. When a snake eats one 10-gram mouse, it gets heavier by 1 gram. So to make a snake grow by one gram, you have to spend 100 grams of grass. 2. http://www.botany.uwc.ac.za/sci_ed/grade10/ecology/images/pyra5.gif If you ignore the "energy stored by" you get the name of each trophic level. By the way, the 4th trophic level consumer is also called a tertiary consumer (final consumers is fine too). Also, primary consumer is secondary producer, and so on. 3. http://en.wikipedia.org/wiki/Carbon_cycle 4. High latitude=high altitude. 100 feet up in altitude is like 1000 miles up in latitude. 3 factors=altitude, latitude, precipitation 5. Metabolism is "is the set of chemical reactions that occur in living organisms in order to maintain life" (wiki). Catabolism=breaking down complex molecules for energy (think "canibalism"). Anabolism=using energy to build complex molecules.

Question:Im talking about energy pyramids. I need at least 3 ways a land food chain and ocean food chain are different and 3 ways they are the same! HELP! NEEDED 2MORROW!!!!!!!

Answers:Who is your teacher? Email Me her name cuz im pretty sure she is mine too.


Answers:Because of the large amount of energy that is lost at each trophic level, the amount of energy transferred gets less and less. There cant be too many levels because the animals at the end of the chain would not get enough energy to stay alive. Primary Producers (100%) --> Primary consumers (10%) ->Secondary Consumers (0.1%) In some cases you can have tertiary consumers and quaternary ones. (total five levels) @}--;- .

Question:Include an example of a food web and trophic level pyramid that would be found in the tundra!! HELP GUYS HELP!

Answers:I am unable to copy and paste the food web and energy pyramid but these links have two excellent diagrams which I guess is just what you need.
