Life Cycles (Science Experiments)
Why should we learn about metamorphosis?
Insects: How does food supply affect the growth rate of grasshoppers or crickets?
All animals go through changes during their lives. Some simply grow larger, while others completely change their forms. This kind of change is called metamorphosisTransformation of an immature animal into an adult., which means "change in form."
Some insects have no metamorphosis, simply growing larger and becoming able to reproduce. Others undergo an , in which the immature insects are known as nymphsAn immature form in the life cycle of insects that go through an incomplete metamorphosis.. Nymphs, which often live in water, resemble the adult forms, but their wings are not fully developed and they have no reproductive organs. Nymphs gradually become adults by , or shedding their outermost layer.
Other insects go through a complete metamorphosisMetamorphosis in which a larva becomes a pupa before changing into an adult form., in which the immature stage is called a . Caterpillars, for example, are the larvae of butterflies. The larva becomes a...
