Terrestrial Biomes Test

Which one of the following is not a terrestrial biome?

Estuary.

True or False? A temperate deciduous forest has little vegetation on the ground because the thick canopy prevents sunlight from reaching the ground.

False; Tropical Rain Forest.

Coniferous trees have leaves that have been reduced to needles. What is the evolutionary advantage to this adaptation?

Prevents water loss Seeds stay on til they have enough water to come off.

What is the adaptive advantage of deciduous trees losing their leaves each year?

Prevents water loss; conserves water.

Tropical Rain Forest.

This biome is characterized by tall trees that form a continuous canopy.

Tropical Rain Forest.

This is the most productive of all biomes due to the year-round growing season and abundant rainfall.

Tropical Rain Forest.

Which of one of the following biomes is considered to be the most productive?

Tropical Rain Forest.

Which biome has the highest species richness of all biomes.

Tropical Rain-forest.

True or False? A taiga is also called a boreal forest.

True.

True or False? Every species of organisms has particular adaptations that make the organisms well suited to a particular environment.

True.

True or False? Permafrost is found only in a tundra biome.

True.

What is the difference between tundra and taiga?

Tundra - dry and frozen; cold Taiga - wet

A very cold and mostly treeless biome.

Tundra.

In this biome, animals include arctic foxes, caribou, snowy owls, and migratory waterfowl.

Tundra.

In this biome, plants include only sedges, lichens and mosses.

Tundra.

In this biome, soil conditions are very poor due to the lack of decomposition.

Tundra.

Plants requiring deep roots cannot grow in this biome because the roots cannot penetrate the soil.

Tundra.

This biome has low temperatures, low precipitation levels and nutrient-poor soil.

Tundra.

This biome is characterized by the presence of permafrost.

Tundra.

This is the largest biome and covers about 1/5th of the world's land surface.

Tundra.

Grasslands are known by what name in southern Africa?

Veldts.

Because of the hot and dry summers and the low-growing shrubs, the risk of fire is high in this biome.

Chaparral.

Which biome has plants that include oily and fragrant wildflowers and herbs, as well as short, spiny bushes.

Chaparral.

Which biome is semiarid and is dominated by low-growing shrubs, and open woodlands.

Chaparral.

Grasslands are known by what name in North America?

Prairies.

Why is the soil so nutrient-poor in a tundra biome?

Because of permafrost and little decay or decomposition.

A system of terrestrial communities that cover a large area and are characterized by certain soil climate conditions, and particular types of plants and animals?

Biome

In a tropical rain forest, what name is given to the dense covering formed by the tops of the very tall trees?

Canopy.

Tropical rain forests are being destroyed at an alarming rate. What might happen to carbon dioxide levels as a result.

Carbon dioxide levels go up Less tress burning releases carbon

Animals in this biome include mountain lions, bobcats, coyotes, deer, rabbits, numerous songbirds, and insects.

Chaparral.

This is a forested biome dominated by cone-bearing evergreen trees.

Taiga.

Both the taiga and the temperate deciduous forest are dominated by trees. How are the trees different in each biome?

Coniferous, spruce, and pines Deciduous; leafy.

What term is used to describe trees that lose of all of their leaves each year during the fall season and regrow them in the spring?

Deciduous.

Animals in this biome include kangaroo, rats, nocturnal animals, many types of reptiles, bighorn sheep, and mountain lions.

Desert.

In this biome, plants include cacti and other succulents.

Desert.

Plants and animals in this biome must have adaptations for conserving water.

Desert.

This biome has high temperatures, low precipitation levels and nutrient-poor soil.

Desert.

This biome receives less than 10 inches of rain per year.

Desert.

Vegetation in which biome is extremely sparse.

Desert.

What name is given to a plant that is not rooted in the soil but instead grows directly on another plant?

Epiphite.

What biome is found just south of the tundra?

Taiga.

Animals that live in savannas:

Must be able to survive periods of drought.

What name is given to the permanently frozen layer of soil in the tundra?

Permafrost.

Why is fire a constant threat in an chaparral?

Plants are oily Dense and low

Animals in this biome include large grazing herds of elephants, giraffes, zebras, as well as lions, leopards, and cheetahs.

Savanna.

This biome has alternating wet and dry seasons.

Savanna.

Which biome has tropical or subtropical grasslands with scattered trees and shrubs.

Savanna.

Plant and animals that survive in a desert have numerous adaptations that enable them to survive.

Spikes and thorns Waxy plants Succulents Nocturnal animals Burrowing animals.

Plants living in a taiga must have adaptations for:

Surviving long and cold winters.

In this biome, animals include moose, bears, beavers, and lynxes.

Taiga.

In this biome, winters are long and cold, but the summers are mild enough and long enough to allow the ground to thaw.

Taiga.

Its plants include pine, spruce, and firs.

Taiga.

Animals in this biome include turkeys, songbirds, deer, squirrels, raccoons, and foxes.

Temperate Deciduous Forest.

Plants in what biome include oak, elm, maple, birch, and hickory.

Temperate Deciduous Forest.

This biome is dominated by trees that lose their leaves in the fall season.

Temperate Deciduous Forest.

This region has four distinct seasons with precipitation distributed evenly throughout the year.

Temperate Deciduous Forest.

This biome has medium temperatures, medium precipitation levels and nutrient-rich soil.

Temperate Grassland.

This biome is dominated by lush grasses and herbs and is often turned into farmland.

Temperate Grassland.

This biome is usually found in the interior of continents where rainfall patterns are too dry to support trees.

Temperate Grassland.

Which biome contains large herds of bison as well as prairie dogs, small rodents, and open woodlands.

Temperate Grassland.

What is the difference between temperate grassland and savanna?

Temperate grasslands - less rainfall. Savanna - Plants grow stronger.

Why do so few trees grow in the tundra?

The ground has permafrost which means there is not enough moisture for most plants to survive.

What distinguishes one biome from another? How are biomes classified?

The plants and animals The soil and the climate.

What is the difference between adaptation and tolerance?

Tolerance - The ability to handle things. Adaptation - Something you are born with that helps you survive.
