Biodiversity increases ecosystems' ability to absorb CO2 and nitrogen
...plant ecosystems were better able to absorb carbon dioxide
(CO2) and nitrogen (N), both of which are on the rise due to human activities and industrial processes. "The key implication of this research is that, in response to elevated levels of CO2 and N, ecosystems with high biodiversity will take up and seq...
