Biology Question on organisms and populations

Sigmoid growth curve is represented by

A

dN/dt=rNdN/dt=rN

B

dN/dt=rN  (1−N/K)dN/dt=rN\,\,(1-N/K)

C

Nt/No+B+I−D−ENt/No +B +I-D-E

D

dN/dt=1−N/KdN/dt=1-N/K

Answer

dN/dt=rN  (1−N/K)dN/dt=rN\,\,(1-N/K)

Explanation

Solution

Sigmoid growth curve is represented by dN/dt=rN(1−NK)dN/dt=rN\left( \frac{1-N}{K} \right) Most populations do not show exponential increase because their environment prevents this.
