Exploring the Grassland Biome and Its Ecosystems

Grasslands are a dominant biome on Earth, covering various climates and regions. They consist of non-woody plants with hollow stems and have evolved over millions of years. Grasslands are found in North America, Eurasia, South America, Africa, and New Zealand, each with unique characteristics. Human activity has transformed many natural grasslands into agricultural lands, yet grasses remain crucial as they form the basis of many cereal crops. The video explores the diversity, distribution, and significance of grasslands, emphasizing their role in supporting biodiversity and human civilization.
