Why would a grass fires caused by lighting srikes would be a useful adaptation for a seed to need fire to sprout?

Grass fires caused by lightning strikes can clear the ground of competing vegetation and create nutrient-rich ash, providing an ideal environment for seeds to sprout. Some seeds have evolved to require the heat or chemical cues from fire to break dormancy, ensuring that they germinate at a time when conditions are favorable for growth. This adaptation allows these plants to thrive in fire-prone ecosystems, taking advantage of the resources made available by the fire. Ultimately, this relationship enhances the survival and reproductive success of these fire-dependent species.
