In which biome does fire seem to be a controlling factor in plant species diversity?

Answer 1

The answer is the savanna biome. Fire is a natural part of the savanna ecosystem and is an important factor in controlling plant species diversity. Fire helps to maintain the open grassland structure of the savanna and prevents the encroachment of woody vegetation. Fire also helps to promote the growth of grasses and other herbaceous plants, which are important food sources for many savanna animals.
