Select all of the following that are true of the savanna biome.
Home to many grasses Found in Africa, Australia, India, and South America Occupy about 20% of the earth's land area
Select all of the following that are characteristics of the taiga.
Long, severe winters Rainfall of 10 inches to 39 inches Dominated by spruce, fir, and pine
The western Cascade Mountains and the western slopes of the Sierra Nevada are characterized by high annual rainfall, frequent fires, and large conifers. This is known as which biome?
Mountain and Coastal Forest
An altitudinal zonation of species, or the change in plant associations as altitude increases, is most commonly found in which biome?
Mountain forest
Select all of the following that are characteristics of the desert biome.
Plants with water storage tissues in stems and leaves Precipitation of less than 5 inches per year Plants with widespread shallow root systems that rapidly absorb water from rain events
This biome occupies roughly 20% of the earth's land area and is characterized by limited rainfall, the presence of many grass species and animals like zebras, elephants and lions.
Savanna
Tundra is characterized by which of the following features?
Summer temperatures can reach 81oF. Permafrost is present. Precipitation is less than 10 inches per year.
Also known as the boreal forest, this biome is dominated by evergreen trees.
Taiga
This biome is characterized by broad-leaved tree species that shed their leaves annually and can be found in North America from the Great Lakes to the Gulf of Mexico and from the Mississippi to the eastern seaboard.
Temperate deciduous forest
Select all the ways that tree species in mountain forests are adapted to fire.
They have thick bark that can be charred without damaging interior tissues. In some instances their seeds germinate best after exposure to fire. Their seedling thrive in areas opened by fire.
Why do many spring flowers complete their life cycles early in deciduous forests?
To take advantage of the opportunity for direct sunlight before the deciduous tree canopy fills in
Which of the following plants usually complete their life cycles before the tree canopy leafs out in temperate deciduous forests?
Trillium Bloodroot
This biome is characterized by 79 to 157 inches of rainfall annually, temperatures ranging from 77 to 95oF, forests of broad-leaved evergreen trees with shallow root systems, hanging vines, and epiphytic plants.

altitudinal zonation of species
A biome has a characteristic mix of plants and ________ adapted to a region's environment.
animals
Soil in tropical rain forests is relatively nutrient poor because ______.
