Document Summary
Constantly changing but possibility to be stable due to equilibrium between reproduction and mortality. Ecological dynamics: study of processes responsible for biological changes and their net effects on populations, communities and ecosystems. (eg. of a process: forest fire) Ecosystems are complex and diverse limited by physical processes species are functional groups linked through biological interactions. Idea of balance in nature, because those systems are regulated. Translate an ecological problem into a model: simplifying assumptions (e. g. individuals are moving super fast they can be anywhere instantaneously. Mathematics (analytical (pen and paper) or numerical (that require computers) Thus here we are looking at the rate of change of predator, Prey: alga dh/dt = eat/reproduce get eaten die da/dt = reproduce get eaten dp/dt = eat/reproduce dire. Assumption: the predator eats only the herbivore, not the autotroph.
