How long do life cycles last for?
Different organisms have different life cycles. The length of a life cycle will depend on the species you want to know about. One life cycle is the time for an individual organism to reach reproductive maturity and reproduce, i.e. produce offspring (children).
The similarities are: 1) Both life cycles start with an egg. 2) Both life cycles are three-stage life cycles. Other than these two, there's no more similarities unless you use general similarities like both life cycles' young goes through a same life cycle as its adult or both life cycles are insects etc. Hope it helped!
