Part 1
(a) Find the values of
p Subscript 1
through
p Subscript 10.
Solution
To solve this logistic growth problem, we use the logistic growth model equation:
where:
- is the growth rate (),
- is the initial population (),
- is the population at generation ,
- is the population at the next generation.
We will compute through step by step using this recurrence relation.
Step-by-Step Calculation
Given :
- Repeat until .
Let’s calculate numerically: Logistic growth model parameters r = 0.8 # Growth rate p0 = 0.7 # Initial population n_steps = 10 # Number of iterations to calculate
List to store population values for p_0 to p_10
population_values = [p0]
Iteratively compute population values
for i in range(n_steps): pn = population_values[-1] pn_next = r * pn * (1 - pn) # Logistic growth formula population_values.append(pn_next)
population_valuesHere are the computed values of from to :
p_0 & = 0.7 \\ p_1 & = 0.168 \\ p_2 & \approx 0.1118 \\ p_3 & \approx 0.07945 \\ p_4 & \approx 0.05851 \\ p_5 & \approx 0.04407 \\ p_6 & \approx 0.03370 \\ p_7 & \approx 0.02605 \\ p_8 & \approx 0.02030 \\ p_9 & \approx 0.01591 \\ p_{10} & \approx 0.01253 \\ \end{aligned}$$ The population quickly decreases with each step under this logistic growth model due to the high initial value of $$p_0 = 0.7$$, which is close to the equilibrium $$p = 0$$. --- Would you like further explanation of these results, or assistance with part (b)? Here are some related questions for you to consider: 1. What is the long-term behavior of the logistic growth model for this system? 2. How does changing the growth rate $$r$$ affect the population trend? 3. What happens if the initial population $$p_0$$ is below 0.5? 4. Can you plot the values of $$p_n$$ over time to visualize the decay? 5. How does logistic growth compare to exponential growth in this case? **Tip:** Logistic growth models are particularly useful for modeling populations constrained by resources or competition!Ask a new question for Free
