Life Cycles

All living things go through changes as they grow and develop. Although individual organisms die, new ones replace them, ensuring the survival of the species. During its life cycle, an organism goes through physical changes that allow it to reach adulthood and produce new organisms. Since these changes are common within a species, they can be grouped into stages of development. The unit Life Cycles addresses the life cycles of plants and animals, including humans.
