The Importance Of Aerobic Life On Earth Essay - 1883 Words

Introduction: Aerobic life on earth is only possible thanks to the oxygen produced by the cellular respiration of plants and other photosynthetic organisms. This crucial service was recently demonstrated in a 2012 study by Martin et al. titled A paradigm of fragile Earth in Priestley’s bell jar. The experiment was based off of Priestley’s now famous bell jar experiment where Priestley first placed a mouse in a sealed jar without plant life, leading to the mouse’s eventual asphyxiation, and placed another mouse in a sealed jar this time with the addition of mint sprigs. This second mouse survived unscathed and in an effort to replicate this experiment on a large scale Martin et al.’s study focused on keeping a healthy 47-year old man in a small, well-lit, and sealed greenhouse filled with a variety of plants for 48 hours. Their experiment was a success and the oxygen content in the greenhouse actually rose from a deliberately reduced initial concentration of 12.4 % O2 to an 18.1 % concentration more representative of our atmosphere. In our study we sought to compare the oxygen output of three different types of photosynthetic organisms, a strain of pea plant, a lichen, and an Elodea sp. to find which species yielded the most oxygen per gram of mass. We hope that the information acquired in our study can be used in a similar way to Martin et al.’s study and hope it will be of especial service those seeking to transport or keep aerobic organisms in confined spaces,Show MoreRelatedIb 150 Exam 11240 Words   |  5 Pages1.

Earth in Equilibrium: The carbon cycle is an environmental cycle that has helped people live on planet earth. Carbon which is a part of the four elements (wind, water, fire and earth) attaches with oxygen in a gas called carbon dioxide.
