Which of the following biomes is dominated by grasses and herbaceous plants, with some trees and shrubs, and characterized by seasonal rains, a pronounced dry season, and often large migratory mammals?
Savanna
Temperate deciduous forest
Tundra
Desert
Tropical rainforest
Explanation
The characteristics listed describe a savanna. Deserts can also have pronounced periods of rain and dryness but are not dominated by grasses and not populated by large migratory animals. Tropical rainforests and deciduous forests are dominated by trees and tundras tend to be colder and may not receive much rainfall, but often have moist soil due to low evaporation rates.

An ecosystem includes which of the following?
Communities and populations
Biomes, communities, and populations
Communities only
Populations only
Biomes and populations
Explanation
Ecosystems are composed of communities and communities are composed of populations. A biome is a larger unit than an ecosystem, as it includes multiple ecosystems.
Which of the following is not an abiotic component of an ecosystem?
Molds
Temperature
Humidity
Minerals
Wind speed
Explanation
Abiotic factors are non-living and molds are living.
Which biome is characterized by hot, dry weather with mild, rainy winters, some vegetation, and occasional fires?
Chaparral
Desert
Savanna
Temperate grassland
Temperate forest
Explanation
The chaparral biome is known for being rather dry and for having these characteristics. They are different than deserts, as deserts do not have a rainy season. While savannas are often warm, they have a longer 6-8 month rainy season.
