Example Questions
Example Question #1 : Ecology
Which biome is characterized by hot, dry weather with mild, rainy winters, some vegetation, and occasional fires?
Chaparral
Savanna
Temperate forest
Desert
Temperate grassland
Chaparral
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.
Example Question #85 : Sat Subject Test In Biology
Which of the following is not an abiotic component of an ecosystem?
Wind speed
Minerals
Temperature
Molds
Humidity
Molds
Abiotic factors are non-living and molds are living.
Example Question #91 : Sat Subject Test In Biology
An ecosystem includes which of the following?
Communities and populations
Biomes and populations
Biomes, communities, and populations
Populations only
Communities only
Communities and populations
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.
Example Question #11 : Ecology
1. Largest biome in the world
2. Short, wet summers and long, cold winters
3. Flora consists of mostly coniferous trees
The given statements most closely describe which biome?
Alpine
Tundra
Deciduous forest
Taiga
Chaparral
Taiga
The taiga biome is the largest biome in the world and is characterized by short, rainy summers coupled with long, freezing winters. Due to its extremely cold temperatures, the taiga's flora or plant life consists of mostly coniferous trees that can survive on the scarce nutrients available in the cold climate of the biome. In contrast, the tundra is frozen year-round and permafrost prevents any trees from growing. Deciduous forests, as the name suggests, sports mainly deciduous trees as its plant life. The alpine biome consists mostly of the areas right below the snow lines of mountains and is generally dry year-round. The chaparral is a relatively small biome that is characterized as being mostly hot and dry year-round, with mild winters.
Example Question #93 : Sat Subject Test In Biology
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?
Desert
Tropical rainforest
Tundra
Temperate deciduous forest
Savanna
Savanna
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.
