Grassland terrestrial biomes are both dependent upon periodic severe drought and/or fire.
Terrestrial biomes are ecosystems that can be found anywhere on earth that has a similar climate pattern and are not necessarily close to one another. Tropical forests are an illustration of a terrestrial ecosystem. Forests, grasslands, deserts, and tundra are some of the different biome types found in the terrestrial environment. There are eight main terrestrial biomes: temperate grasslands, temperate forests, boreal forests, Arctic tundra, and tropical rainforests, savannas, subtropical deserts, and chaparral.
The grassland biome consists of terrestrial areas where grasses predominate and there aren't many big trees or bushes. Temperate grasslands, tropical grasslands (sometimes called savannas), and steppe grasslands are the three main types of grasslands.
