Planakton study
Keystone species
disporportionaly large effects on their communities

commensalism
competition
using the same resources

superior competitor forces other organism out
chracter displacement
strong selection against competitor
must evolve to survive

herbivory
predation
parisitism
consistuative defense

(camouflage, schooling, weaponry)
