c. tundra

Identify this biome

SAVANNA GRASSLANDS

Which biome has year round warm temperatures and relatively constant precipitation. The vegetation is stratified, and competition for light is intense. Epiphytes generally cover the forest trees. This biome has the highest diversity of animals than any other biome.


c. tropical rain forest

Which biome is characterized by long, cold winters. Plants include cone bearing trees such as pine, fir, and spruce. The conical shape of these trees prevents too much snow from breaking their branches. Mammals found in this biome include moose, brown bears, and Siberian tigers.

a. temperate grasslandb. taiga c. tropical rain forestd. deserte. tundra

b. taiga

Which biome is characterized by an extensive canopy that allows little light to penetrate to the ground and by the presence of epiphytes? (Activity: Aquatic Biomes)

Which biome is characterized by an extensive canopy that allows little light to penetrate to the ground and by the presence of epiphytes?


c. tropical rain forest

Which biome has plants that include cacti, deeply rooted shrubs and herbs that are able to grow quickly during infrequent moist periods. Adaptations for plants in this biome include heat and desiccation tolerance, water storage, and reduced leaf surface area. Physical defenses such as spines, and chemical defenses such as toxins in leaves are also common. Many of the plants exhibit C4 or CAM photosynthesis.


d. desert

Which of these is the largest terrestrial biome on Earth?

a. tundrab. coniferous forestc. temperate broadleaf forestd. temperate grasslande. desert b. coniferous forest

Which biome has moderate climate with four distinct seasons. The dominant plants are deciduous trees, which drop their leaves before winter. Many animals hibernate in the winter and bird species migrate to warmer climates.

a. temperate grasslandb. coniferous forestc. tropical rain forestd. temperate deciduous forest e. tundra

d. temperate deciduous forest

Desert owls are inactive during the day and active at night. This describes an adaptation to which biome?

Which one of the following biomes is dominated by gymnosperm or conifer trees (pines, firs, spruces)?

a. taigab. tundrac. desertd. broadleaf foreste. tropical rain forest

a. taiga

In which one of the following biomes would you expect decomposers to work most rapidly and efficiently?

a. tundrab. savannac. desertd. taigae. tropical rain forest

e. tropical rain forest

Which biome is characterized by high winds and cold temperatures. Winters are long and cold and summers are short and cool. The dominant vegetation is herbaceous and includes plants such as lichens, mosses and grasses which do not grow tall due to the high winds and permafrost. Mammals found in this biome include caribou, reindeer, bears, wolves and foxes.


e. tundra

Which biome is warm year round, but has more seasonal variation than tropical rain forest. Dominant plant species are grasses with scattered trees, which are adapted to seasonal droughts and fires. Large herbivore mammals such as wildebeests and zebras and their predators are common inhabitants. During seasonal droughts, grazing animals must migrate to other parts of this biome with more food and scattered watering holes.

a. temperate grasslandb. coniferous forestc. savanna d. deserte. tundra

c. savanna
