Foliage refers to the collective leaves of plants, trees, and shrubs. It plays a crucial role in photosynthesis, the process by which plants convert sunlight into energy. Foliage can vary in color, shape, and size, contributing to the overall appearance of a landscape. In addition to its biological functions, foliage provides habitat and food for various animals, including insects and birds. Seasonal changes can dramatically alter foliage, as seen in autumn when leaves change color and eventually fall, enriching the soil. Healthy foliage is essential for maintaining ecological balance and supporting biodiversity.
