Bio - discussed ecological succession, from pioneer organisms to their effect of changing the soil to (given that seeds from other species reach the soil in that area) new and more complex species successfully reproducing in the area to the eventual stable ecosystem of the climax community. If a climax community is destroyed, SECONDARY succession begins and eventually a SIMILAR climax community forms (given the same type of climate and abiotic factors).


We reviewed the evolutionary mechanism of competition as part of natural selection and saw how the similarity between species niches determines the level of competition and eventually the rate of evolution (of those species).

We discussed the various biomes on Earth and the typical species that are best adapted to their niches in those biomes.
