Answer:
Growth hormones are produced by the body to allow for growth. The amount of hormone produced determines how large an organism and the parts of the organism grow. If everything happens as planned, then the organism will be proportional and will not have any misshapen organs. A growth chart for humans is shown to the left. All creatures go through different growth stages. Normally, the growth during these times is regulated by a growth hormone; however, things sometimes do not happen the way they should.
To conserve resources, organisms reproduce with immature and small copies of themselves. Without straining the parent organism, these small copies gather their own resources to grow, enlarge, mature, age, and reproduce themselves. Humans are excellent examples of growth and development. Eventually, organisms die, returning their gathered resources to the earth for reuse by new organisms. The cycles and stages of life are growth and development.
