Document Summary
Division of resources (example: the right side go to the right tree and left side go to left tree) takes place as postulated and it reduces competition. By removing the birds species (yellow birds), the black birds start expanding and grow. Lack of completion = more resources = more abundant species = inc of species fitness. Carbon, water, hydrogen and nitrogen (which is hard to obtain) are needed to make protein! Epiphytes are plants that grow on other plants, not parasites. They climb on other plants to get sun for photosynthesis. Biophysical research: example release of co2 in the environment. Likens and borman added nutrients to the ecosystem the forest died b/c it was a herbicide instead that killed the forest. Comparison of two streams (one stream was subjected to our treatment and the other was not touched). Less o2 in the sediments so sediments are preserved. That"s how coil is preserved not enough time to decompose from organic matter.
