2.
a limiting factor whose effect changes when the population density changes
3.
a limiting factor whose effect does NOT change when the population density changes
4.
an abrupt event in an ecosystem that suddenly and significantly changes the resources available, the number/type of organisms, or the kinds of species present
5.
the natural process in which a disturbed area is gradually taken over by a species/groups of species that weren't there before
6.
The rate of change in a population over specified amounts of time
7.
ecological succession that starts in an area where there are essentially no living organisms
8.

9.
ecological succession that occurs in an area where there is some component of the ecosystem, including soil, remaining after a disturbance
10.

11.
a relationship in which one species benefits, while the other species does not benefit but is not harmed (it's unaffected)
12.
a relationship in which both species benefit
13.
a relationship in which one species benefits, while the other species is harmed, but not killed
14.
an interaction where one organism hunts, kills, and eats the other organism
15.
