Seeds can be dispersed in several ways, including through wind, water, animals, and gravity. Wind-dispersed seeds are lightweight and equipped with structures like wings or hairs that help them float through the air. Water-dispersed seeds can float on water, allowing them to be carried long distances. Animals like birds, mammals, and insects can also inadvertently carry seeds on their fur, feathers, or in their digestive systems, helping to spread them to new locations. Additionally, some seeds rely on gravity to fall from their parent plant and settle on the ground where they can germinate.
