All living things are made of carbon. Learn how carbon moves through Earth's ecosystems and how human activities are altering the carbon cycle. The carbon cycle. Plants use carbon dioxide and sunlight to make their own food and grow. Biogeochemical cycles . The plants that undergo Calvin cycle for carbon fixation are known as C3 plants. The carbon cycle. Where the carbon is located — in the atmosphere or on Earth — is constantly in flux. Biogeochemical cycles overview. The nitrogen cycle. The water cycle. The Carbon Cycle. They take carbon dioxide (CO2), sunlight, and water and turn it into oxygen and sugar. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. These processes are sometimes called carbon sinks. This is the currently selected item. Learning Objectives. Because the Earth is a dynamic place, carbon does not stay still. In the atmosphere, carbon is attached to some oxygen in a gas called carbon dioxide. The water cycle. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change. Diagram of the Carbon Cycle Click on picture to see larger view Taking Carbon out of the Atmosphere Nature is constantly taking carbon out of the atmosphere. Then students are introduced to the carbon cycle and create a simple model to diagram their understanding of carbon’s movements through Earth’s four major reservoirs: biosphere, lithosphere, hydrosphere, and atmosphere. The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. The carbon cycle. Google Classroom Facebook Twitter. The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere , pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Email. It is on the move! Intro to biogeochemical cycles. After this lesson, students will be able to: define and explain the carbon cycle ; demonstrate understanding of the carbon cycle by creating a visual representation Students use labels and arrows to represent processes that move carbon from one reservoir to another. Calvin Cycle requires the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase commonly called RuBisCO. Carbon is also a part of the ocean, air, and even rocks. Photosynthesis - Plants use photosynthesis to make energy and grow.
