chapter 6 --> environmental science
biomes that are located between 30* north latitude and 30* south latitude might be
tropical rain forests
which biome has the largest number of species
tropical rain forests
which of the biomes receives 200 to 450 cm of rain per year?
tropical rain forests
a biome that has a large amount of rainfall, high temperatures and poor soil is a
tropical rainforest
which biome is the wettest?
tropical rainforest
permafrost can be found in which of the following?
tundra
which biome is the coldest?
tundra
which of the following biomes has been affected by human activity ?
tundra, chaparral, and temperate grassland
when does climate get colder?
when either latitude or altitude increases
As you walk through the forest on a chilly day, you can hear the fallen leaves crunch underfoot. This forest is located
at about 40* north latitude
on page 157, know figure 3.5. she said it will be on test. know the cm, soil, and names. click: okay
okay
where do epiphytes grow?
on the sides of trees. (example: moss)
what are three characteristics of tropical rainforests
rain, temperature, and temperature
migration of animals in the savanna is mostly a response to
rainfall
climate
refers to the weather conditions, such as temperature, precipitation, humidity, and winds that occur in an area over a long period of time
describe how savannas differ from temperate grassland
savannas have scattered trees here and there, while grasslands have only a thick density of grass and do not have trees
Biomes with higher temperatures and less precipitation tend to have
shorter and less dense vegetation
what are the adaptations that plants have in a particular biome?
size, shape, and how they manage water
temperate deciduous forests
trees drop their broad, flat leaves each fall. these forests once dominated vase regions of earth, including parts of north america, europe, and asia
approximately what percentage of earth's species do tropical rainforests contain
50%
what do temperate grassland vegetation consist of?
grasses and wildflowers
canopy
Dense covering formed by the leafy tops of tall rain forest trees
emergent layer
The tallest layer of the rain forest that receives the most sunlight. can reach heights of 60 to 70 cm
tundra
a biome that is located in northern arctic regions. the winter is too cold and dry to permit the growth of trees in this biome
biome
a large region characterized by a specific type of climate and certain type of plants and animal communities
chaparral
a temperate shrubland biome that is found in all parts of the world with a mediterranean climate. these areas are moderately dry, coastal climates, with little or no rain in the summer
conifer
a tree with needle like leaves and seeds that develop on cones
savanna
a tropical biome dominated by grasses, shrubs, and small trees.
tropical rain forest
always humid and warm and get about 200 to 450 cm of rain a year. they help regulate world climate and play vital roles in the nitrogen, oxygen, and carbon cycles
deserts
areas that have widely scattered vegetation and receive very little rain. in extreme cases, there is no rain and no vegetation
understory
below the canopy, very little light reaches this level
what type of light does the emergent layer get?
bright light
spadefoot toads survive the dry conditions of the desert by
burrowing themselves in the ground
How are biomes described?
by their vegetation because the plants that grow in a certain region are the most noticeable characteristics of that region
what is a common adaptation of chaparral
camouflage, which is shape or coloring that allows an animal to blend into its environment
the tundra is most suitable to a vertebrate that
can migrate hundreds of kilometers each summer
which of the following is located primarily in coastal areas with Mediterranean climates?
chaparral
which of the following best describes the relationship among latitude, altitude, and climate?
climate becomes colder as you move up a mountain
the most common types of plants in the taiga biome are
coniferous trees
temperate grassland
covers large areas of the interior of continents, where there is moderate rainfall but trees and shrubs cannot be established because there is not enough rain or fires are too frequent
which biome is located b/w 30* and 60* latitude?
grasslands
describe two ways in which tropical rainforests of the world are being threatened
deforestation and exotic animal trade
what type of light does the understory layer get?
dense light
which biome is the driest?
desert
describe how a plant survives the change of seasons in a temperate deciduous forest.
drop leaves and goes dormant
what type of light does the canopy layer get?
filtered light
why are periodic fires important?
fires are an important part of temperate grassland ecosystems. burns away old life to create new life
animal species of the tropical rainforest ....
have adaptations that minimize competition
permafrost
in arctic regions, the permanently frozen layer of soil or subsoil
when does habitat destruction occur?
it occurs when land inhabited by an organism is destroyed or altered
the distance north or south of the equator, as measured in degrees is. called....
latitude
you are walking through a forest that receives relatively little rainfall and has acidic soil. this forest is located in a region
near the arctic circle
you are walking through a forest with the greatest species diversity. this forest is located in a region
near the equator
temperate rain forests
occur in North america, australia, and new zealand. have large amounts of precipitation, high humidity, and moderate temperatures
what adaptations do desert animals have to help them survive?
sweat glands and burrowing
which biome is just below the arctic circle?
taiga
which biome has the most fertile soil?
temperate grassland
which of the following receives about 25 cm of rain per year
temperate grassland
which biome contains large trees
temperate rainforest
the main factor that determines what type of plants grow in a biome is
temperature and precipitation
the two main factors that determine where organisms live are
temperature and precipitation
latitude
the distance north and south of the equator and is measured in degrees with the equator equal to 0 degrees
altitude
the height of an object above sea level
animals such as pronghorn antelope, bison, and badgers dot the landscape. where are these animals located?
the north american prairie
taiga
the northern coniferous forests that stretches in a broad band across the northern hemisphere just below the arctic circle.
you are 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
