Answer:

Metamorphosis is another word for the changes an animal makes during its life cycle. During a frog's metamorphosis, an egg will hatch into a tadpole, which will then develop back legs first, then front legs, and become a full grown adult frog!

Once weaned, piglets are placed in a nursery until they are approximately 8-10 weeks of age. The last stage in pig production is known as grow-finish, or fattening, when pigs are fed until they reach market weight. Pigs are normally sold for meat at five to six months of age (older in some countries).
