Bees play a crucial role in ecosystems as pollinators. By transferring pollen from one flower to another, bees enable plants to produce fruits and seeds. This process supports not only plant life but also the animals and humans that depend on these plants for food. Without bees, many crops would fail, leading to a significant decline in food supply. Efforts to protect bee populations, such as planting wildflowers and reducing pesticide use, are essential for maintaining biodiversity and food security.
