chapter 6 biomes

Animals that live in the desert

are usually nocturnal

Adaptations of desert animals that help them survive in the hot, dry desert often include

searching for food at night

you walking through a forest that gets large amounts of rain, has high humidity, and has moderate temperatures year-round. where is this forest located

the pacific northwest

describe two ways in each tropical rain forests of the world are being threatened.

trading and habitat destruction

tropical rainforest

wettest biome

As you walk through the forest on a chilly day, you can hear the fallen leaves crunch underfoot. This forest is located

where annual rainfall is 200 cm

bright light

emergent layer

Name the main layers of a tropical rain forest. what kinds of plants grow in each layer

emergent layer - tallest trees canopy - trees understory - shrubs

Grassland

located between 30 degrees and 60 degrees latitude

Taiga

located just below the arctic circle

near the equator

(tropical; rain) forest

how are tropical rain forests and grasslands threatened by human activities? Give one example for each biome.

1. deforestation, habitat destruction, trading 2. overgrazing, farming, habitat destruction

explain the difference between a biome and an ecosystem.

A biome is different from an ecosystem. An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there

how are tundra biomes and desert biomes similar?

A desert and a tundra are similar in that both of these regions receive little precipitation, have somewhat limited vegetation and experience cold temperatures at night. Along with forest, aquatic and grassland, tundra and desert are among the five major biomes on Earth.

Taiga is

A forested biome dominated by coniferous trees

a forest that receives relatively little rainfall has acidic soil would be located near the_______________

Arctic circle

describe three ways that desert organisms can adapt to survive in their environment

Being nocturnal Waxy leaves to keep moisture in scaly skin

why are former grasslands among the most productive farming regions? Explain your answer.

They have deep rich topsoil.

Plants in a particular biome have ___________ that help them to survive in that biome.

adaptation

tropical rain forest are being destroyed primarily by logging for lumber and to create open land for__________

agricultur

Grasslands, such as the prairies of North America,

are threatened by soil erosion because native grasses have been damaged or destroyed by plowing and overgrazing

Most of the animals in the tropical rain forest live in the ___________layer, where fruits and flowers and abundant.

canopy

filtered light

canopy

the________layer of a tropical rain forest receives the most sunlight

canopy

which of the following is located primarily in coastal areas that have Mediterranean- style climates with warm, dry summers and mild, wet winters?

chaparral

which of the following best describes the relationship among latitude, altitude, and climate?

climate becomes colder as you move up a mountain

Tundra

coldest biome

tropical rain forest are threatened by

deforestation and the trade of rain forest plants and animals.

Animals that burrow would most likely be found in a

desert

what biome has annual rainfall of less than 25 cm.

desert

Latitude

distance north or south of the Equator, measured in degrees

desert

driest biome

which of the following would you expect to see in the emergent layer of a tropical rain forest?

eagles, bats, and snakes

the deforestation of the rain forests may cause climate changes which, in turn, may affect

flooding

Many forest biomes are experiencing __________ destruction, when land inhabited by an organism is destroyed or altered.

habitat

list three characteristics of tropical rain forests.

humid, near the equator, and the most biodiversity

If you visited a savanna, you would likely see

large herds of grazing animals, such as rhinos, gazelles, and giraffes.

you are walking through a forest with the greatest species diversity. this forest is located in region

near the equator

Deserts are

often formed on the dry side of mountain ranges

in the tundra, the frozen layer of soil just beneath the surface is called the__________

permafros

animals such as pronghorn, bison, and badgers live on the North American_____________

prarie

Biomes with higher temperatures and less precipitation tend to have

shorter and less dense vegetation

which of the following best describes a tropical rain forest?

species of animals with specialized ways of surviving in order to avoid competition

Arctic

taiga

During harsh winters, animals of the _____ have adaptations such as the ability to change color to avoid predators

taiga

which of the following biomes receives 200 to 450 cm of rain per year

taiga

the climate of a biome is determined mostly by average__________and precipitation

temperature

the main factor that determines what type of plants grow in a biome is

temperature and precipitation

biomes that are located between 30 degrees north latitude and 30 degrees south latitude might be what?

tropical rainforest

Due to the extreme temperature conditions and simple, easily disrupted food chains, the __________ is very sensitive to human disturbance.

tundra

As you travel from the North Pole toward the equator, you would expect to see

tundra, then grasslands, then tropical rain forests

dense shade

understory

Biomes are classified and often named according to their ____________________, which determines which other organisms that can live there.

vegetation
