Unformatted text preview: f) Real curves are S shaped. g) None of these numbers are constant, any environmental factor can cause changes h) Ex. Predation, disease ect. i) If 90% of the ground is gone, then 90% of the population is dead, it doesnt matter how big the initial population was. j) Basically, they are things that cannot respond to the changes in population density. (independent) k) Prey/predators have a feedback loop with a delay (lag) on it. l)...
