Ecology-The study of the interaction among organisms and their biological and physical environment. Organization of Ecological study Biosphere Ecosystem(Large and Small) – Community Population Individual Characteristics of Ecosystems 1) Energy Sources- Autotrophs- photosynthetic plants that fix energy of sunlight and Heterotrophs those that cannot make energy, but derive energy from Autotrophs 2) Energy Flow Structure-a) Abiotic- non living component, physical characteristics, b)autotrophs, (producers), c)heterotrophs (consumers) d)decomposers (recyclers)
