unlimited growth that is "J-shaped" exponential growth
limited growth that is "S-shaped" logistical growth

the increase of toxins as you go up the trophic levels biomagnification
both organisms benefit mutualism
one organism benefits and other is not helped or harmed commensalism
one benefits and other is harmed parasitism

succession where soil and some organisms remain secondary succession
species that tells the overall health of ecosystem indicator species
species that is important to maintaining a species keystone species
