Sigmoid growth curve is represented by
A
$d N / d t=r N$
✓
$d N / d t=r N(1-N / K)$
C
$N t=N_{o}+B+I-D-K$
D
$d N / d t=1-N / K$
✓
Answer
Correct option: B.
$d N / d t=r N(1-N / K)$
b Sigmoid growth curve is represented by $d N / d t=r N(1-N / K)$ Most populations do not show exponential increase because their environment prevents this.
