Which biome has a characteristic flora that includes grasses, shrubs, and few trees, with a small amount of rainfall?

The correct choice is indeed the savanna biome, and it is defined by its unique climate and vegetation structure. Savannas are characterized by a mix of grasses and scattered shrubs or trees, which allows for a diverse range of flora adapted to the relatively low rainfall. This biome typically receives seasonal rainfall, meaning there are distinct wet and dry periods, which is not conducive to dense forests but supports the growth of grasses and a few scattered trees that are often drought-resistant.

In a savanna, the adaptations of the plants enable them to survive in conditions that can be dry for extended periods. For instance, many grasses have deep root systems that allow them to access moisture below the surface, while individual trees, like the acacia, may have broad canopies that reduce water loss. The limited tree coverage, contrasted with the vast expanses of grass, is a defining feature of savannas.

The other biomes mentioned have different characteristics due to their climates. Temperate deciduous forests receive more rainfall and have a wider variety of tree species that lose their leaves in fall. Tropical rainforests are known for their dense tree coverage and high rainfall, creating a lush environment with little sunlight reaching the forest floor. The taiga, or boreal forest,
