Fire helps to maintain the existence of grasslands andsavannas.Fire plays a crucial role in the ecological dynamics of certain biomes, particularly grasslands and savannas.Theseecosystems have adapted to periodic fires, which are often ignited by natural causes such as lightning strikes or by human intervention.The presence of fire in these biomes influences vegetation composition, nutrient cycling, and overall ecosystem health.In grasslands, fires help to control the growth of woody plants and maintain thedominanceof grass species.Fire removes accumulated dead vegetation, stimulates the germination of seeds, and promotes the growth of new shoots. It also recycles nutrients back into the soil, allowing for nutrient-rich regrowth.Similarly, in savannas, fire plays a vital role in maintaining the balance between grasses and trees. Regular fires prevent the encroachment of trees and help sustain the characteristic open canopy structure of savannas.Fire removes excess plant material, reduces competition for resources, and supports the growth of grasses and fire-adapted plant species.However, it's important to note that fire management practices should be carefully implemented to ensureecological sustainabilityand the safety of human populations living in or near these biomes.To know more about "Savannas" refer here:brainly.com/question/29881906##SPJ11...
