A population with $\mathrm{N}=400$ individuals increases in numbers till it reaches an asymptote at $\mathrm{K}=500$ individuals, K being the carrying capacity. Assuming the intrinsic rate of natural increase ( r ) to be 0.01 , what would be the population growth rate $(\mathrm{dN} / \mathrm{dt})$ ?

• Correct answer
  A

  $0.8$
• B

  $1$
• C

  $0.05$
• D

  $0.4$

Hence, the correct answer is option: 'A'.
