Why does some plant seeds need fire in order to germinate?

Some plant seeds require fire to germinate because the intense heat can break down tough seed coatings or trigger chemical changes that promote germination. Fire can also clear competing vegetation, allowing seedlings to access sunlight and nutrients in a less crowded environment. Additionally, certain plants have adapted to fire-prone ecosystems, relying on the periodic occurrence of fire to stimulate their reproductive processes and ensure successful propagation.
