ecology???
Ecology (from Greek oîkos, "house"; -λογία, -logos, study of) is the interdisciplinary scientific study of the distribution and abundance of organism and their interaction with their enfironment .The environment of an organism includes all external factors, including abiotyc ones such as climate and geology, and biotic factors, including members of the same species (conspecifics) and other species that share a habitat. If the general life science of Biology is viewed as a hierarchy of levels of organization, from molecular processes, to cells, tissues and organs, and finally to the individual, the population and the ecosystem, then the study of the latter three levels belongs within the purview of ecology.
