How do grasses survive fires that happened in grasslands?
Small animals can climb underground into their burrows to stay safe, but grasses and other plants common to grasslands can’t run away. Instead, they are specially adapted to survive fire.

How do grasses survive the fire in Savanna?
And equally importantly, fires in the Savanna burn mainly dry grasses that regrow each year: the carbon dioxide released by fires in grasslands is reabsorbed by the growth of new grass the next year, meaning such fires are nearly carbon-neutral within a year.
