1: Examine the Terrestrial Carbon Cycle food web diagram again. Create your account. For this activity, study the scrambled letters and try to unscramble or rearrange the letters to form a word or phrase that fits the given clues. The _____ process is described as the breaking down of dead organic substances that eventually become part of the soil. study Working Scholars® Bringing Tuition-Free College to the Community, Discuss the importance of carbon in the world, Describe how carbon is recycled through organisms. The carbon cycle is essentially nature's way of reusing carbon atoms in different ways and in varying places. Use specific evidence from the diagram to support your answer. Select all the answers that are correct and then click the Check Answers button at the bottom of the list. This passport chart will be the record of your journey through the carbon reservoirs. credit-by-exam regardless of age or education level. succeed. What is the main source of carbon in an ecosystem? Similarly, we have a fixed amount of carbon on Earth and in the atmosphere. When the leaves fall to the ground, they will eventually decompose. With a pencil and an eraser, neatly write your answers in the appropriate blank spaces in the clues. Sequence of processes through which carbon Sequence of processes through which carbon compounds Sequence of processes through which carbon compounds move from one carbon reservoir Sequence of processes through which carbon compounds move from one carbon reservoir or sink (such as forests and oceans) to another (such as atmosphere) and back. In Lab 1, you learned about the molecular nature of carbon compounds and the carbon cycle, and its relationship to other biogeochemical cycles such as the nitrogen cycle. The stations you see posted around the classroom represent reservoirs of carbon typically found in a forest ecosystem. _____ that live for a long period could trap carbon. The continuous circulation of carbon in various forms through nature is known as _____ _____. Then, you will take on the role of a carbon atom moving throughout a Lodgepole Pine forest ecosystem. The _____ that plants use to make sugar compounds are CO2, sunlight, and water. imaginable degree, area of Would a pre-industrial carbon cycle be in balance or out of balance? When they are taken out of the ground and burned for fuel, they become a carbon source. The carbon cycle overlaps the rock cycle. Are fossil fuels and land use change(deforesting forests for agriculture) currently behaving as a carbon sink or a carbon source? Identify any carbon cycle processes you would expect to see operating on a global spatial scale that also operates in a forest carbon cycle. _____ _____, the world's primary energy source, are derived from prehistoric remains of living organisms. Then, check your understanding of how carbon moves through food webs by answering the. Anyone can earn Climate and the Carbon Cycle: Unit Overview, World's forests' role in carbon storage immense, research reveals, Carbon sink found underneath world's deserts, Lab 4: Deforestation and the Carbon Cycle, Lab 8: Slowing Down an Amplifying Greenhouse Effect, When soil microbes (bacteria and fungi) decompose dead material, they break down larger carbon compounds into smaller compounds. Which biosphere process(s) is responsible for moving 450 Gt of carbon per year from the atmosphere into the vegetation and land? But there is one element on the periodic table that is absolutely crucial to every living organism. © copyright 2003-2020 Study.com. Thus, you can see how carbon moves throughout our world and affects each and every organism. The other major way that carbon is cycled through living organisms is through decomposition. Soil microbes, the smallest organisms in the food web, have one of the most critical roles in transforming and moving carbon compounds through food webs and ecosystems. Remember that carbon atoms move as part of a carbon compound, not as single atoms. Their role is threefold: Check your understanding of how carbon moves through food webs by answering the questions below. What is the relationship between the oxygen cycle and the carbon cycle?
