Ecology In predator-prey relationships, the number of animals in each category tends to vary periodically. A certain region has pumas as predators and deer as prey. The equation P=500+200sin[0.4(t−2)] models the number of pumas after t years. The equation D=1500+400sin(0.4t) models the number of deer after t years. How many pumas and deer will there be in the region for each value of t? t=10
