Document Summary
Ls7b monday reading carbon cycle the intricately linked network of biological and physical processes that shuttles carbon among rocks, soil, oceans, air, and organisms. The chemistry of life is, to a first approximation, the chemistry of carbon. How organisms move carbon from one species to another, and between organisms and their surrounding environment, underpins both the efficient functioning of ecosystems and their persistence over an immense span of time. In no small part, biological diversity can be understood in terms of the varied ways that organisms obtain the carbon needed for growth and reproduction. Summertime removal of co2 from the atmosphere does not quite balance winter increase, with the result that the amount of co2 in the atmosphere on any given date is greater than it was a year earlier. Atmospheric co2 levels have therefore increased steadily through the period of monitoring.
