The significance of seed dispersal in plant ecology lies in its role in promoting genetic diversity and colonization of new environments. Through various mechanisms, such as wind, water, animals, or gravity, seeds are transported away from the parent plant. This reduces competition for resources between seedlings and parent plants, enhancing survival rates. Dispersal also allows plants to reach suitable habitats, helping them adapt to changing environmental conditions. Furthermore, it plays a crucial part in ecosystem dynamics, influencing community structure and interaction among species.
