Question

Describe briefly: Sigmoid growth curve.

Answer 1

The growth of living organisms in their natural environment is characterised by an S-shaped curve called sigmoid growth curve. This curve is divided into three phases – lag phase, log phase or exponential phase of rapidgrowth, and stationary phase.

Answer 2

Explanation:The growth curve of any organism appears to have a sigmoidal curve which includes lag phase, log phase, stationary phase and the death phase. The lag phase is the adaptation phase for the organism where they acclimatizes themselves to the new environmental conditions provided. The growth is slow at this stage.
