Document Summary

First law of thermodynamics-increase of internal energy of system equals the amount of heat added to the system minus the work done by the system. Second law of thermodynamics-when energy is transformed, the quantity of energy remains the same but its ability do to work diminishes. Nt=noe^rt exponential logistic decreases k-selected r-selected other constant decline of survivorship type iii ex: squirrel when predator"s population increases, prey"s population overshoot-population goes over the carrying capacity die off-population crash. Predation temporal-use the same resource at two different times spatial-use two different habitats morphological-evolution of a difference in body shape or size. Oscillates around the k small organisms, reproduce often with large numbers of offspring type ii ex: rat abundance determined by k large organisms, reach reproductive maturity late, produce few offspring type i ex: killer whale. Predation-(+, -)one species uses another species as a resource. Parasites-live on host but only consume a small part of it.
