Learning About Types Of Biomes And What Lives There A biome is a large area characterized by its vegetation, soil, climate, and wildlife. there are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga. Vocabulary. the desert biome covers about one fifth of earth’s surface. this biome has a layer of soil that can either be sandy, gravelly, or stony, depending on the type of desert. deserts usually get at most 50 centimeters (20 inches) of rainfall a year, and the organisms that live in deserts are adapted to this extremely dry climate.
Newsela What Makes A Biome Grassland biomes consist of large open areas of grass. trees can be present, but they are infrequent. the animals found in grasslands range from african elephants (loxodonta africana) to various species of prairie dogs (cynomys spp.). low rainfall, wildland fires, and grazing by animals are three factors that maintain grasslands. The main characteristic of deserts is a shortage (or complete lack of) precipitation; some desert regions go for years on end without rain. other characteristics of deserts include extremes of temperature and very little plant growth. the desert biome consists of species able to live in these inhospitable conditions. This chapter describes some of the major terrestrial biomes in the world; tropical forests, savannas, deserts, temperate grasslands, temperate deciduous forests, mediterranean scrub, coniferous. A biome is an area classified according to the species that live in that location. temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome. however, scientists disagree on how many biomes exist. some count six (forest, grassland, freshwater, marine, desert, and tundra.
