Of the four ecosystem processes, community dynamics is the most vital. Water and minerals cannot cycle effectively and solar energy cannot flow through life unless plants of some form - algae to trees - first convert sunlight to useable energy for life and cover the soil. For this reason it is imperative that we learn to maintain healthy biological communities whether they be associated with grasslands, forests, rivers, lakes, coral reefs, or oceans….
