Document Summary

Higher diversity more plant species more niches greater variety of food less competition for resources more food available less harsh environment (abiotic) in forest. Stable ecosystem, if the population of one species changes, alternative food sources are available. Many species have adaptations that allow them tosurvive, including many producers. Higher solar energy input gives more light for photosynthesis (and higher temperatures) Lower diversity less plant species less niches smaller variety of food higher competition for resources less food available more harsh environment (abiotic) in forest. Unstable ecosystem, change in the population of one species affects populations of other species. Only a few species have adaptations that allow them to survive. Process in which different species make up a community over time. Autogenic succession: brought about by plants only. Allogenic succession: external factor (eg flooding) alters development of community. 1 succession / succession where no living organisms have been found before.
