Which statement best describes a grassland biome?

• A. Warm temperatures
• B. Moderate rainfall (has grass but it is yellow)
• C. Grasses dominate, few trees
• D. Herbivores dominate

Answer: (D)

Grasslands are defined by grasses forming the dominant plant life, with only a few scattered trees. This dominance happens because the climate—moderate to low rainfall and periodic disturbances like fire and grazing—favors grasses over woody plants, allowing grasses to persist and shape the ecosystem. Herbivores are abundant in many grasslands and play a crucial ecological role, grazing and influencing vegetation patterns, but the defining feature is the plant community where grasses dominate. The statement that best describes a grassland is that grasses dominate with few trees, highlighting the plants that define the biome rather than focusing on animal numbers.
