Ecology: Elementary factors
Josep Peñuelas1 & Jordi Sardans1
Abstract
The identification of a general connection between biogeochemistry and the structure of food webs would constitute a considerable advance in understanding ecosystems. Ecologists are on the case.
Organisms are the products of chemical reactions, and their growth depends on the availability of various elements, especially carbon, nitrogen and phosphorus. The growth-rate hypothesis1 links the relative element content of organisms to their growth rate, the idea being that fast-growing organisms need relatively more P-rich RNA, the main component of the protein-producing ribosome, to support rapid protein synthesis.
