Answer
Four methods of seed dispersal are: 1. Wind Dispersal: Seeds are carried by the wind, often aided by specialized structures like wings or fluffy hairs. 2. Animal Dispersal: Seeds are transported by animals through consumption and excretion, attachment to fur or feathers, or caching. 3. Water Dispersal: Seeds float on water and are carried to new locations by rivers, streams, or ocean currents. 4. Mechanical Dispersal: Seeds are ejected from the plant through mechanisms like bursting or snapping. These methods help plants spread their seeds to various locations and increase their chances of successful germination and growth.
