Document Summary

Midterm: cumulaive (weighted on second half), quesion period tba. Sunlight makes energy readily available -> it is taken in (via photosynthesis) by primary producers -> they are consumed by primary consumers (only 10% energy is passed on through trophic levels) Diversity shits from physical constraints (e. g. climate, global paterns of movement of water) to bioic constraints at the more focused level. R species: energeically cheap ofspring, small organisms, many ofspring. K species: compeitors, larger organisms, fewer, more energeically costly ofspring. As we move from early to later successional stages, compeiion increases. Frederic clements: communiies are highly organized and persist over long periods of ime. Henry gleason: communiies are the sum of independent species response to the environment over ime. Individualisic concept ; communiies are accidents, interacions are amongst individuals only, constant change. Succession sequenial change in the relaive abundance of dominant species in a community following disturbance. (energy low, compeiion) Primary succession: community develops from essenially abioic condiions.
