Ecology

Ecology (from Greek: οίκος, oikos, "household"; and λόγος, logos, "knowledge") is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their Ecosystem includes both physical properties, which can be described as the sum of local abiotic factors such as insolation (sunlight), climate, and geology, and biotic factors, which are other organisms that share its habitat. The term oekologie was coined in 1866 by the German biologist Ernst Haeckel.
