LIFE CYLCES describes and illustrates three different types of life-to-death-to-life again cycles that occur in nature. First is the cycle of the sunflower that grows from a seed to maturity, thus producing more seeds to begin the cycle again. Next is the mushroom cycle, involving the production of spores as a means of reproducing. The third life cycle is that of the grasshopper, which produces eggs that, once fertilized, hatch into new grasshoppers. Each of these examples is a variation of the eternal circle of life and death that is characteristic of most types of plants and insects.
