PPT-12A Interpret relationships (predation, parasitism, commens

An organisms role in its environment An organisms habitat is the area where it lives In any environment every species fills a unique niche A niche includes the conditions and resources a species needs for survival and how it obtains these resources. Can you think of examples of relationships where both people/ organisms benefit?. Can you think of examples of relationships where one organism benefits while the other is harmed?.
