Answer:

There would be 60 deer after 1 year

Step-by-step explanation:

When a population is growing in a constrained environment with capacity K, and absent constraint grows exponentially with growth rate r, then the population behavior can be represents by the logistic growth model,

P_n = P_{n-1}+ r(1-\frac{P_{n-1}}{K})P{n-1}

Where,

P_{n-1} = previous year population,

r = growth rate per year,

K = Capacity,

Here,

P_0 = 40, r = 50\% = 0.50, K = 2000

Thus, the population of deer after 1 year,

P_1=40+0.50(1-\frac{40}{2000})40

=40+0.50(\frac{2000-40}{2000})40

=40+0.50(\frac{1960}{50})

=40+19.60

=59.6\approx 60

Answer:

p= 50

Step-by-step explanation:
