Conservation biology is the effort to study, preserve, and restore threatened species, populations, communities, and ecosystems. Def: study of the relationship between organisms and their environment, where the environment is composed of. Abiotic (physical factors air, water, wind, temperature) and biotic (living factors species, habit) factors. Another def: study of the distribution and abundance of organisms. Organisms interact with their environment at different hierarchical levels. The e(cid:374)(cid:448)iro(cid:374)(cid:373)e(cid:374)t is the (cid:373)a(cid:272)roha(cid:271)itat arou(cid:374)d the site arou(cid:374)d (cid:449)here the i(cid:374)di(cid:448)idual"s orga(cid:374)is(cid:373)s li(cid:448)e/(cid:271)reath/reside. Hierarchical level are both a matter of special scale and also level of organization we make definitions about (individuals, population, ecosystems). What do you think is the main difference between these definitions of ecology answer is related to spatial scales of investigations. Organismal ecology study of the morphological, physiological, and behavioural adaptations that allow individuals organisms to live in a particular area.
