Name: _____________________________________________________ Date: ____________________ Energy in the Ecosystem Webquest Directions: This webquest has been designed to review you on a variety of ecological concepts including trophic levels, food chains, food webs and ecological pyramids. While on your Quest, record your answers on the Answer Sheet. 1. The following link will take you to a short YouTube clip that will explain to you the difference between autotrophs and heterotrophs. https://www.youtube.com/watch?v=eDalQv7d2cs a. Once you have watched the clip answer the questions below by filling in the missing spaces within the table Ecological Term Definition Example Autotroph Heterotroph Herbivore Omnivore Carnivore Decomposer b. Green plants (autotrophs) get their energy through a complex process known as what? __________________________ c. Autotrophs take solar energy and transform it into a sugar known as what? ____________________________________ d. Herbivores, omnivores and carnivores are all examples of AUTOTROPHS or HETEROTROPHS (Circle One) 2. The relationships between the organisms represented by the ecological terms defined in question #1 can be represented through a food chain. The next link will take you to the food chain game, and remember; it’s eat or be eatin’. http://www.sheppardsoftware.com/content/animals/kidscorner/games/foodchaingame.htm a. Draw one of the food chains that you completed within the game. 3. The next link will take you to an interactive food web FLASH. A reminder for this interactive, the original arrows stemming from each organism mean “eats.” Drag the arrow to the organism that is being eaten, i.e. the mouse eats the plant. After you have correctly matched the organisms, the arrows will flip so that they correctly represent a food web. http://teacher.scholastic.com/activities/explorer/ecosystems/be_an_explorer/map/line_experiment14.swf a.
