24-25 - there are multiple ways through which Biosphere afftects climate of a region . Biosphere consists of plants , animals , human beings and other living organisms . example of the same is Plants - take out carbon dioxide from the atmosphere and infuse our atmosphere with oxygen during the process of photosynthesis ... where every the density of plants and trees is higher the climate will have a cooler afftect and the air around the region will be much more healthy and cleaner .. plants to exhale carbon dixiode during night but the same is released in a very small quantity .. plants take in much more amount of carbon dixiode during the day time .
