The document summarizes the life cycle of a frog in 4 stages: 1) Eggs are laid in water and hatch into tadpoles within 6 days. 2) As tadpoles, they grow tails and gills to live in water over 60-84 days. 3) They develop legs and lungs and transition onto land. 4) They complete their transformation into adult frogs that live on land and can swim but no longer resemble tadpoles.
