In-Class Worksheet #5 - The Carbon Cycle Worksheet Learning Outcome: Integrate knowledge of Earth’s carbon cycle to demonstrate how carbon moves throughout the spheres and affects global climate and climate change. Directions: You must make your own copy of this google doc. To do this, go to the menu and hit “File” and then select “ Make a Copy”. You must rename this document as your First and Last name followed by “GEOG107 Worksheet #6”. Once you have completed this worksheet you need to upload it to the eCampus assignment submission for “October 18 The Carbon Cycle Worksheet”. Define the following terms in your own words: 1) Carbon cycle - is the process of carbon atoms becoming reused as they move in a circular pattern in earth and the atmosphere. 2) Photosynthesis - the process by which plants use carbon dioxide, sunlight, and water to process food/sugars. 3) Net Primary Production - amount of carbon that is produced by autotrophs 4) Respiration - process of using oxygen to break down food to get energy which results in carbon dioxide and water. 5) Carbon sink - matter that gathers and stores carbon for a period of time 6) Carbon sequestration - storing carbon process Identify the following statements as True or False (write true or false next to each statement). NEW: for False statements, you need to also add the correct information: 7) Carbon coming from burned fossil fuels enters the atmosphere at a slow rate. False 8) Carbon is a powerful greenhouse gas. True 9) Net primary production controls how much carbon is removed from the atmosphere. True 10) The carbon cycle is when carbon atoms move between the Earth and outer space. False 11) Land contains most of the carbon on Earth. False 12) Exam #2 is on Thursday October 27th. True Fill in the blank with the appropriate concept/term learned in this lecture: 13) The [atmosphere] is crucial in linking carbon exchanges between the ocean and land. 14) The four major limitations to net primary production are [ temperature, light, nutrients,water]. 15) Half of all anthropogenic carbon has been released in the past [30] years. 16) [food carbon webs] are an example of how different ecosystems offset carbon emissions. 17) Plants pull carbon dioxide from the atmosphere through the process of [photosynthesis] to produce food. 18) [c02] is the primary greenhouse gas which sets the temperature of Earth. Answer the following questions based on what we learned in this lecture: 19) Why do we care about carbon? It’s a greenhouse gas that effects are day to day life. 20) Give an example of how carbon moves from living things (plants, animals) to the atmosphere. The example needs to be SPECIFIC and described as a sentence, not just one word. Carbon is a food chain to plants to animals, by putting carbon into the ground from fossil fuels. Burned fossil fuels go into the atmosphere which results in c02 and water. 21) Name the three different actors within a food (carbon) web, including the role that each one plays. Producers, consumers, and decomposers. 22) Why is it concerning that amounts of carbon dioxide in the atmosphere are increasing? Because too much carbon dioxide is a product of climate change.
