Seeds disperse in nature through various methods such as wind, water, animals, and gravity. Wind-dispersed seeds are lightweight and equipped with mechanisms like wings or hairs to be carried by the wind. Water-dispersed seeds float and are carried by water currents. Animal-dispersed seeds have adaptations like hooks, spines, or tasty fruits to be carried by animals that eat them or stick to fur. Gravity-dispersed seeds simply fall to the ground and rely on gravity to move away from the parent plant.
