John Lee Mrs. Tanner AP Bio p.4 December 16, 2010 Prelab 12 A 1. What is the biological importance of carbon and oxygen cycling in ecosystems? Carbon and oxygen cycling is important to ecosystems. Living organisms like animals take oxygen from the atmosphere (or from water) and use it for?respiration. During respiration, oxygen is converted into carbon dioxide and water. Carbon is important to the ecosystem because carbon forms the framework for the organic molecules essential to all organisms.
