between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from the German Oekologie or Ökologie) to describe complex systems of life both extant and extinct. These interactions

Ecology EQ’s 2. Abiotic and biotic components influence each other. For instance‚ temperature (abiotic factor) can make plants (biotic factor) reproduce more or reproduce less. Also water‚ an abiotic factor‚ has an effect on how animals‚ a biotic factor‚ survive in certain areas of the world. 3. Because a different niche allows multiple species of organisms to coexist. If all organisms had the same niche‚ then there would be heavy competition for food‚ shelter‚ etc. Having different niches gives
