Logistic (S-shaped) growth form

• Limiting factors (environmental resistance) can transform the J-shaped curve into an S-shape

  
• An S-shaped growth form, also known as logistic growth form, occurs when a young population consisting of only a few individuals is located in an area with sufficient food, water, space and very little predation
• Logistic growth form is characteristic of vertebrates
• Four distinctive phases can be gedistingeerd on the logistic curve:

  Lag phase

  Geometric/accelerating growth phase

  Decelerating growth phase

  equilibrium phase
