Document Summary

Competition: contest for limited resource, what are some of the limited resources over which organisms compete, light, nutrients, water, space, pollinators. Mechanisms of competition: try to get there first so no one can take the resource: exploitation, getting to library first to get book first. Interference: e. g. damage them, harm them in some way: tearing study book in half and putting in garbage. Milkshake analogy: limited resource: the milkshake, competition: if one sibling gets more the other gets less, exploitation: drink faster. Add in number of species of competing species. Competition coefficients (effect of species 2 on species 1) Competition coefficients (effect of species 1on species 2) Population size goes up or down: below isocline-move to right, above, move to left. Answer is d: need to know abundance answer changes depending on where you start. Second one : isocline blue is outside of orange isocline. When cross and carrying capacity are inside, we get stable equilibrium.
