What is the carbon cycle? Why is it important? - Answer The carbon cycle is the mouvement of carbon between species, the earth, the atmosphere and oceans. Without carbon, ecosystems would not function and persist over time. Most exchanges involve the ocean. What are the crucial processes in the carbon cycle? Why are they important? - Answer Cellular respiration and photosynthesis. They cancel each other out so that there isn't too little CO2 (causing a frozen earth) or too much CO2 (causi...
