Open in App
Solution

J-shaped curve:

  1. A graph curve that depicts the situation in which an organism's population density increases rapidly in an exponential or logarithmic form in a new environment, but then abruptly stops.

S-shaped curve:

  1. A growth pattern in which, in a new environment, an organism's population density increases slowly at first, in a positive acceleration phase; then rapidly, approaching an exponential growth rate.
J-shaped curve S-shaped curve
1.It represents exponential growth .1.It represents a sigmoidal growth of the population
2.It has limited resources. 2. It has unlimited resources.
3.It consists of lag and log phases .3.It also includes a deceleration phase.
4.It doesn't reach the stationary phase .4.Stationary phase is achieved .
