PPT-Predicting predator-prey populations

Desired results Heres an approximation of reality The hare birth rate is constant as their food supply is unlimited Hares only die when eaten by a lynx and the number of hares eaten is proportional to how often hares amp lynxes meet ie the chance of a lynx catching a hare.

Natality-. the birth rate; the number of births over time. Mortality-. the death rate; the number of deaths over time. Rates That Affect Population Size. Immigration-. Introduction. Before you begin predict what will happen to the camouflage and visual acuity scores of the prey and predator over 10 generations. . Write . a hypothesis in your lab notebook.. Game set up. Richard Peters. ES 314. Sonoma State University. Cellular Automata. “A cellular automaton is a collection of "colored" cells on a grid of specified shape that evolves through a number of discrete time steps according to a set of rules based on the states of neighboring cells. The rules are then applied iteratively for as many time steps as desired.”. 7.EC.5B.1 Develop and use models to explain how organisms interact in a competitive or mutually beneficial relationship for food, shelter, or space (including competition, mutualism, commensalism, parasitism, and predator-prey relationships)..
