Question:
Calculate the population changes for 5 generations in a hypothetical predator-prey system with discrete generations in which the following parameters for the prey are: B = 0.03, Neq = 100, C = 0.5, and the starting density is 50 prey. For the predators, S = 3, and starting density is 0.2. Round to the nearest individual for the PREY popualtion and round to TWO decimal places for the PREDATOR population.
After 5 generations, the prey population size "N" is ________________ and the predator population size "P" is_____________________.
What type of oscillation does the prey population exhibit (from the previous question) and what will this tell you about the long term outcome of this predator-prey relationship?
A. No oscillations, both populations maintained indefinitely with no cycling.
B. Chaotic fluctuations, because the predator population relies on the prey population, and we see large chaotic fluctuations in both population sizes. Though, long term, both species would die out.
C. Convergent oscillations, both populations would be maintained indefinitely but would see spikes in both population sizes followed by a decrease in size that are much smaller in magnitude.
D. Stable limit cycle, both populations would be maintained indefinitely but would see spikes in both population sizes followed by a decrease in size.
