The word "ecology" was coined in 1866 by the German biologist Ernst Haeckel, from two Greek words: oikos, meaning house or habitat, and logos, meaning science. Ecology thus appears as the science of habitats, studying the living conditions of organisms and the interactions of all kinds that exist between these organisms and their environments. It seeks to understand the mechanisms that allow different species of organisms to survive and coexist by sharing or competing for available resources (space, time, energy, matter)
