007 – Ecosystem Ecology

In this video Paul Andersen explains how ecosystems function. He begins with a description of how life on the planet is ordered from large to small in biomes, ecosystems, communities, population, and individuals. He describes the major terrestrial and aquatic biomes on the planet. He then describes interactions at the ecosystem level with food food webs. He also explains the importance of niche, keystone species, and the edge effect.
