Study of interactions between organisms and enviro. Interactions happen within and among hierarchal scales. Organisms pop commun ecosystems (commun + water, weather, Doesn"t have much of indy life, bound to colony. Plant fungi on these leaves to eat. There is a parasite that attacks this fungus. Bacteria in ant bodies to kill parasite. Simple prokaryotic cells organized eukaryotic cells simple multicellular organisms complex multicellular organisms simple societies complex societies. Simplest ecosystem= indy organ + enviro interactions. Pop= indys of same species, process of evolution. Commun= diff species in one place, process of generating biodiversity. Biosphere= global movement and location of life, air, water, nutrients, energy, global processes of stability and change. Humans are unique in that they have power in changing ecosystems. Chem rxns are the same at all levels. All life on earth share common metabolic processes. Metabolic theory of ecology= all share common constraints on metabolic rate. Ecological stoichiometry= balance of elements and resulting chem rxns gov ecosystems.
