The carrying capacity for a pop. is estimated at 500; the pop. size is currently 400; and r=.01 whats dN/dt?

Question

a. 0.01

b.0.8

c.8

d.40

e.50

anybody please answer this question correctly i would be really grateful

Answer 1

Next time to help out the answers, it would be best to include the equation or its name. Good thing I have no life. I believe this is the equation you need:

dN/dt = (rmax) *N *((K-N)/K)

K = carrying capacity N = population size  

rmax= intrinsic rate of increase

dN/dt= population growth rate

dN/dt = (.01)(400)((500-400)/500)

dN/dt = 0.8
