What is a biome?
Biomes are very large ecological areas on the earth. They are filled with many different species of flora and fauna. Biomes are often classified by abiotic factors; climate, soils and vegetation, and the animals that adapt to that particular environment.
What is a grassland biome?
Grasslands are biomes that:
There are two types of grassland, temperate grasslands and savanna. Temperate grasslands often have much greener grass but trees and shrubs are almost absent; while savannas have browner grass and scattered individual trees. These are often found in Africa, covering almost half the surface. Grasslands are a major part of the global ecosystem, covering 37% of the earths terrestrial area. For a variety of reasons, mostly relating to overgrazing and the resulting problems of soil erosion and weed encroachment, many of the world's natural grasslands are in poor condition and showing signs of degradation. Grasslands make a significant contribution to food security through providing part of the feeding requirements of animals used for meat and milk production. Globally this is more important in food energy terms than pig meat and poultry meat. |
