Ecological maxims (guiding principles): organisms interact and are interconnected, everything goes somewhere, no population can increase in size forever. Mohammed sarikahya: finite energy and resources result in tradeoffs, organisms evolve, communities and ecosystems change over time, spatial scale matters. Population: group of individuals of a species that are living and interacting in a particular area. Community: association of populations of different species in the same area: ecological studies often include both the biotic (living components), and abiotic (physical components) of natural systems. Ecosystem: community of organisms plus the physical environment. (abiotic + biotic) Landscapes: areas with substantial differences, typically including multiple ecosystems: all the world"s ecosystems comprise the biosphere all living organisms on earth plus the environments in which they live.
