It is, however, not possible simply to extend this to terrestrial systems, which are far more complex in their structure. In terrestrial systems there are two parallel cycles, a short cycle and a long; in the s

In this process, atmospheric CO. is taken up by the chloroplasts and, with the aid of absorbed light energy, is converted to organic compounds, mostly carbohydrates; during this process storage of chemical energy takes place. Intermediate compounds with three carbon a

The Competitive Factor and Root Competition, these are of importance only indirecily in that they affect the competitiveness of the plants. Only at the absolute limits of distribution, in arid and icy deserts, at the edge of the salt desert or where the forest shade is deepest—in other words, where competition is absent—do environmental facto
