How can dispersal methods increase a species' range?

Dispersal methods play a crucial role in increasing a species' range by allowing seeds or offspring to spread to new areas. When seeds are dispersed away from the parent plant, they have the potential to germinate in various environments, which can lead to the establishment of new populations in previously unoccupied habitats. This not only helps the species colonize new areas but also reduces competition for resources with the parent plant and its immediate surroundings.

The ability of seeds to travel, whether through wind, water, animals, or other mechanisms, enables them to reach diverse ecosystems where they may thrive. This can enhance the species' survival and adaptation by increasing its chances of finding suitable conditions for growth, reproduction, and ultimately, the expansion of its geographic range.

In contrast, other options relate to aspects that do not directly contribute to extending the distribution of a species. For example, limiting genetic diversity would hinder adaptability and resilience, enhancing soil nutrients focuses on soil health rather than dispersal, and slowing down growth would adversely affect a plant's ability to establish in new areas.
