Daisy and Julie talk about grasslands after Daisy's absence from school. Grasslands developed in areas with environmental conditions between forests and deserts. They contain a nearly continuous cover of grasses and support various herbivores and predators. Temperate grasslands experience distinct seasons with hot summers and cold winters, while tropical grasslands have rainy and dry seasons without spring or fall. Common plant species in grasslands include types of grasses like big bluestem and varieties of bamboo.
