It describes why grasslands cover a large share of Earth’s land, which distinctive plants and animals they support, and how climate factors like low rainfall, drought, and frequent fires limit tree growth.

grass and fertile(rich)soils.A grassland environment is part of an ecosystem.An ecosystem ismade up of living plants and animals and their non-living environmentof air,water,energy,and nutrients.  \nGrasslands occupy about a quarter of the world's land surface.  \nThey are home to many unique plants,insects,mammals,birds,reptiles,and other animals.Some grasslands have huge herds of grazing animals,such as antelope,zebra,cattle,and sheep.  \nLow rainfall,droughts,and frequent fires stop large areas of treesfrom growing in grasslands.Because they have fertile soils,manygrasslands have been cleared to grow important cereal crops,such as wheat and maize.These cleared areas are known as theworld's \"breadbaskets,\"because they supply food for the world.  \nMost grasslands are found between deserts and forests.  \n# Where Do Grasslands Grow?\n\nGrasslands cover almost half of the ice-freeland on Earth.They grow on everycontinent except Antarctica.G","cbCaibacPKHr8VKk","https://ap.wps.com/l/cbCaibacPKHr8VKk","pdf",2944396,"English","# What Are Grasslands?\n## Where Do Grasslands Grow?\n## Types of Grasslands\n## Threats to
