Oxygen makes up nearly 20% of the atmosphere. Use the following information to calculate the residence time of oxygen in the atmosphere. Mass of oxygen in atmosphere = 1.4 million gigatonsMajor sources of oxygen to atmosphere:Photosynthesis by plants on land = 125 gigatons/yrPhotosynthesis by plants in ocean = 155 gigatons/yrMajor sinks of oxygen from atmosphere:Respiration by animals = 220 gigatons/yrBacteria = 50 gigatons/yrBurning of fossil fuels = 10 gigatons/yr
