In which biome do animals graze and grains grow?

The biome where animals graze and grains grow is the grassland biome, which includes savannas and temperate grasslands. These regions are characterized by vast open spaces dominated by grasses, making them ideal for grazing animals such as bison, antelope, and various livestock. Additionally, the nutrient-rich soil found in these areas supports the cultivation of grains like wheat, barley, and oats. This combination of grazing and agriculture is vital for both wildlife and human food production.
