1. Dispersal by wind: Many plants, especially those with small seeds, use the wind to carry their offspring far from the parent plant. Examples include dandelions, milkweed, and maple trees. Some animals, like spiders and small insects, can also use the wind to travel long distances, often attached to silk or other materials.

2. Dispersal by water: Plants and animals that live near water can use currents or tides to disperse. Seeds can float on water, and some aquatic animals, like fish and invertebrates, can travel long distances in the water.

3. Dispersal by animals: Many plants and animals rely on animals to help them disperse. Plants might produce fruit that is attractive to animals, which eat the fruit and then deposit the seeds in their droppings elsewhere. Other animals, like birds, can carry seeds or small insects on their feathers. Some animals, like ants, can help disperse seeds by carrying them to their nests.
