GMAS Biology Practice Test

The question is about recognizing a biome that fits a warm climate with a pronounced wet and dry season, where grasses dominate and trees are scattered rather than forming a continuous canopy. In this tropical wet-and-dry climate, periodic fires and grazing keep trees sparse, allowing grasses to thrive across large areas. This creates a landscape of tall grasses with widely spaced trees, often called a tropical grassland or savanna. It’s distinct from deserts, which have extremely low rainfall and almost no vegetation; the taiga, which is a cold boreal forest; and temperate forests, which occur in temperate zones with different seasonal patterns. So, tropical grassland best matches grasses with scattered trees adapted to a tropical wet and dry climate.
