You should now be on the Types of Rocks page. Read the section and answer these questions.What are the 3 main types of rocks?What are sedimentary rocks made of?Give 1 interesting fact about each type of rock.Igneous:Sedimentary:Metamorphic:Give 1 example of each type of rock.Igneous:Sedimentary:Metamorphic:What are the key characteristics used to identify rocks? (Scroll down to the What to Look For section)Energy Pyramids WebQuest a. Fill in the missing spaces within the table:Trophic LevelDefinitionExample(from a single food chain)Producer( aka Primary Producers) Primary Consumer Secondary Consumer Tertiary Consumer Quaternary Consumer b. Critical Thinking: If an organism occupies the secondary consumer trophic level within a given food chain, is that organism always going to occupy the secondary consumer trophic level in other food chains. Provide an example in your response to support your thinking. The ecological concept commonly referred to as the “Rule of 10” is in reference to how efficient energy is passed from one trophic level to the next. Visit the next resource to learn more about the “Rule of 10.” a. The “Rule of 10” states that as little as ________ % of the energy at any trophic level is transferred to the next trophic level. b. If I am a higher trophic level organism, this means that I need to eat MORE / LESS (circle one) food in order to fulfill my energy needs. c. The majority of the energy is lost as ________________ through the completion of metabolic processes.Matter Cycling Web QuestThe Carbon Cycle ()310515015049500 In what form is carbon in the atmosphere?How does carbon move from the atmosphere to plants and then from plants to animals?How does carbon move from plants and animals to the ground?How does carbon move from living things to the atmosphere? What is the process called?How much carbon is released each year from burning fossil fuels? Where does the carbon go? The Nitrogen Cycle () Nitrogen is a component of what 3 building blocks of life?What makes nitrogen in the atmosphere (N2) unavailable for use by living organisms?Briefly define and distinguish between: Nitrogen fixation:Denitrification:Nitrification:Phosphorous Cycle IntroductionUse the following websites to answer the questions: Phosphorus is an important chemical for plants and animals. It is part of DNA, certain fats in cell membranes, bones, teeth and shell of animals. Phosphorus circulates through water, the Earth's crust, and living organisms. It is not in the atmosphere and is most likely to enter food chains following the slow weathering of rock deposits. Some of the released phosphates become dissolved in soil water which is taken up by plant roots. Phosphorus is therefore the main limiting factor for plant growth in most soils and aquatic ecosystems. Animals obtain phosphorus by eating plants and/or herbivores. Dead organisms and animal wastes return phosphorus to the soil, to streams, and eventually to ocean floors as rock deposits. Explain why phosphates are a critical part of life. How is the phosphorus cycle different from other biogeochemical cycles? ExplainThe largest reservoir of phosphorus is in ____________________________ rock. Explain how phosphorus travels through the cycle from rock to omnivores. Why are excessive concentrations of phosphorus sometimes considered a pollutant? How do humans contribute to these excessive levels of phosphorus? ECOLOGICAL SUCCESSION WEBQUEST. What is ecological succession?2. How is primary succession different from secondary succession?3. How is primary succession similar to secondary succession?4. What is the first group of organisms to colonize an area called?5. Which species are able to live on bare rock?6. What situations/conditions lead to the start of primary succession?7. What situations/conditions lead to the start of secondary succession? ................
