What is metamorphosis
Metamorphosis is the process of transformation of the egg to an adult through various changes in morphology at various stages. It takes place in insects and amphibians.
It may be incomplete or incomplete.
1) Incomplete or Direct – It takes place in three stages.
2) Complete or Indirect- It takes place in four stages.
The main difference is that complete metamorphosis consists of a very active, ravenously eating larva and an inactive pupa whereas incomplete metamorphosis consists of a nymph, which resembles a miniature adult.
