Homework Answers
1. Answer: Option B
is correct
Explanation:
The predator-prey populations exhibit a complementary peak
behavior.
Predator = The Arctic fox
Prey = Lemmings
As the number of Lemmings increase, it would result in a subsequent
increase in the Arctic fox population.
Add Answer to:
In the predator/prey model example of Arctic Fox vs Lemmings, it would be expected that as...

5) Explain your answer for question #4 by ahowjng
mathematically the conditions for predator-pret coexistence; and
use your graph to explain why current abundaces od prey and
predator you indicated in #4 indicate cowxistence or not

Problem 1 In simple predator-prey models, sinusoidal functions can be used to model the oscillating populations of two species of animals in the same environment. As the population of the predator species increases, the population of the prey species will decrease. If the number of prey gets too low, the population of the predator species will suffer from limited resources and start to decline. In this problem we will be modeling one population of rabbits (the prey) and one population...

A. Model (graph) a one predator -two prey relationship with foxes, rabbits, and grouse. - Assume that the grouse play the same role as the rabbits. - Assume that food supply for both rabbits and grouse is unlimited. - Assume that foxes do not prefer one prey over the other. B. Introduce food competition between rabbits and grouse. Now graph this. How does this change from the first graph??

Assume a predator and its prey are interacting according to the basic Lotka-Volterra model. The prey population size is 1000, the predator population size is 10, the prey population’s intrinsic rate of growth is 0.1, the predator’s capture efficiency is 0.01, the predator’s assimilation efficiency is 0.2, and the predator’s mortality rate is 0.3. a. Under these conditions, what are the instantaneous growth rates of the prey and predator populations? b. If r, c, a, and m remain stable, which...

However, the predators change in a different manner. Show that if there are many predators for each prey, then the predators cannot cope with the excessive competition for their prey and die off. On the other hand if there are many prey for...
