Patterns in nature refer to the recurring designs and structures found in the natural world. These patterns can be seen in various forms, such as the spiral shapes of seashells, the branching of trees, and the symmetry of flowers. They often arise from mathematical principles, like the Fibonacci sequence, which describes how many plants grow and how sunflowers arrange their seeds. These patterns serve important functions in ecosystems. For example, the stripes of a zebra can help with camouflage, while the hexagonal shapes of honeycombs maximize space and efficiency for bees. Understanding these patterns helps scientists learn more about biology, ecology, and the interconnectedness of life.
