Ecology Unit © It’s Not Rocket Science 2016 16 Practice: Geochemical Cycles Part 1 Read each statement and place a check mark in the column of the cycle(s) it applies to Water Carbon Nitrogen 1. Matter cycles through living and nonliving components of the ecosystem. 2. Cannot happen without decomposers like bacteria. 3. Has stages that occur underground. 4. Matter takes on different chemical forms as it cycles. 5. Entire cycle is driven by the sun. Part 2 Match the name of the stage to the correct description. Not all words will be used. 6. When water returns to the atmosphere via plants. 7. A step in the carbon cycle that didn’t really exist before the industrial revolution. 8. When nitrogen gets captured from the atmosphere by bacteria or even lightning. 9. Water is absorbed underground and can be stored in aquifers. 10. Water is not absorbed underground but collects on the surface of the earth. 11. Fungi and bacteria return nutrients from dead organisms to the soil. 12. Bacteria in the roots of plants convert nitrogen into usable forms, such as NO 2 . 13. Organisms eat other organisms as a food source. 14. Organisms capture sunlight and store the solar energy as chemical energy in molecules like carbohydrates. 15. When nitrogen is returned to the atmosphere by bacteria as N 2 . 16. Water falls from the sky as snow, sleet, or rain. 17. When organisms breakdown carbon-based molecules for energy and release CO 2 as a result. A. Evaporation B. Transpiration C. Condensation D. Precipitation E. Runoff F. Infiltration G. Combustion H. Photosynthesis I. Cellular respiration J. Consumption K. Decomposition L. Fossilization M. Nitrogen fixation N. Ammonification O.

Ecology Unit © It’s Not Rocket Science 2016 17 Investigation: Ecosystem in a Bottle In Class Project Overview Overview: Students will create an ecosystem simulation using 2-Liter bottles to explore the cycling of the essential elements carbon, hydrogen, oxygen, and nitrogen through biotic and abiotic components of an ecosystem. Students will need a minimum of two 2-Liter bottles for this project – one to represent an aquatic ecosystem and one to represent a terrestrial ecosystem. Students will work with a partner to design a way to connect these two bottle ecosystems so that nutrients can cycle appropriately and life can be sustained for a month-long period. They will assemble their ecosystems in class and collect daily observations throughout this month. At the completion of their observation month, students will write a report of their findings, relating their observations back to what they know about the cycling of nutrients and the interrelationships of organisms.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
