Answer

Fire produces ash. When this ash mixes with soil, it enriches the soil with plant nutrients. Therefore, if a seed were to germinate in soil after a fire, it could have an advantage, as the soil will be nutrient-rich. Such seeds might ultimately have an advantage in specific habitats, such as forests, where periodic fires are frequent.
