Principles of ecology.This chapter has a lot of definition need to be know. Abiotic factor are non living part of enviroments such as temperature water sunlight wind rocks and soil periodic disturbances https://classconnection.s3.amazonaws.com/665/flashcards/2470665/png/abiotic_factor1362439889644.png Homeostasis is dynamic balance of processes,materials and organisms in the ecosytem and biosphere Microbes also have roles in the ecosystems oxygen producer. Half of oxygen produce by blue-green algae in the ocean.I wonder how this algae can produce oxygen?Does it has same process as in tree? fix nitrogen in the atmosphere into usable form recyclers of dead materials source in food chain contribution to evolution:remove weaker species through infections What I have learn: -Ecology is the systematci study of organisms and their interactions with enviroment -Example of decomposer is fungi -blue-green algae produce oxygen
