Predator - Prey Dynamics: Rats and Snakes (Lotka Volterra Simulation)

1. What is the primary objective of the Lotka–Volterra predator–prey model?

a: To calculate the carrying capacity of predators Explanation

Explanation

b: To describe the interactions and population dynamics of predator and prey species Explanation

Explanation

c: To estimate the genetic diversity of prey populations Explanation

Explanation

d: To determine the migration rate of predators Explanation

Explanation

2. According to predator–prey theory, what is the most likely consequence if the predator population decreases drastically?

a: The prey population immediately becomes extinct. Explanation

Explanation

b: Predator reproduction increases immediately. Explanation

Explanation

c: The carrying capacity of the habitat decreases. Explanation

Explanation

d: The prey population is likely to increase due to reduced predation. Explanation

Explanation

3. According to the theory, predator and prey populations generally exhibit:

a: Cyclical oscillations in population size Explanation

Explanation

b: Constant population sizes over time Explanation

Explanation

c: Independent population fluctuations Explanation

Explanation

d: Continuous exponential growth Explanation

Explanation

4. According to the Lotka–Volterra assumptions, predator reproduction is:

a: Controlled by seasonal rainfall. Explanation

Explanation

b: Independent of prey availability. Explanation

Explanation

c: Determined only by carrying capacity Explanation

Explanation

d: Directly proportional to the amount of prey consumed. Explanation

Explanation

5. According to the theory, why do predator populations usually decline after a prey population crash?

a: Predators become more efficient at hunting. Explanation

Explanation

b: Food availability decreases, reducing predator survival and reproduction. Explanation

Explanation

c: Carrying capacity suddenly increases. Explanation

Explanation

d: Prey begin reproducing more rapidly Explanation
