description of the climate at Location Z on the
graph?

A marsh is a wet environment that is often found
near a river or lake. Which of the following best
explains how a marsh is able to allow low growing
plants with short roots, such as grasses,
to live there?
It has a lot of water near the top of the soil for
the plants to take in through their roots.
It has a large amount of rainfall that the plants
are able take in through their leaves.
It has algae, a very tiny living thing that is like a
plant, to use as food for the small plants.
It has murky water, shading the plant roots, to
protect them from burning in the sunlight

biome?
tropical rain forest
tropical savannah
desert
grassland

that helps classify an ecosystem?
wildlife
elevation level
soil type
dominant tree species
Which of the following is the transition zone
where freshwater enters the sea?
coral reef
estuary
tidal prism
D. land bridge
Plants with long roots and thick bark have
adapted to which characteristic of the savanna
biome?
large diversity of hooved herbivores
seasons with little rain and forest fires
competition with many other plants for sunlight
moderate climates without extreme
temperatures.
Cacti are plants that have long roots, waxy
leaves, and swollen trunks that are used to
retrieve and store water. A population of cacti
would most likely be found in a
cold and wet environment.
dark and humid environment.
bright and humid environment.
hot and dry environment.
A tropical rain forest is able to meet the needs of
many plants, animals, insects, and birds because
temperatures are
warm all year, and there is a lot of rainfall.
warm all year, and there is little rainfall.
cold all year, and there is a lot of rainfall.
cold all year, and there is little rainfall.
A desert environment, which
is home to many lizards, small mammals, cacti
and other plants with short roots allows some plants and
animals to live there because the soil in the
desert is
dry and sandy, allowing small animals to burrow
and hide from the Sun while allowing plants with
short roots to reach and hold onto water.
wet and hard, allowing small animals to rest and
stay cool on the wet soil while allowing plants
with short root systems to push through the hard
soil to soak up water
cold and wet, allowing small animals to remain
cool when it rains while allowing plants with
short root systems to easily push through sandy
soil to soak up water.
dry and hard, allowing small animals to lay on
the hard soil to get sunlight while allowing plants
with short roots to sit on top of the soil and hold
onto water.
The pictures show close-up views of a fir tree and
a cactus.
Both trees have adapted to their environments.
The fir tree stores water in its needles so that it
can survive winter, when most available water is
frozen. The cactus stores water in its stem so
that it can survive seasonal droughts, when little
water is available. In which biomes can the fir
tree and the cactus most likely be found?
The fir tree is in the rain forest biome,
and the cactus is in the taiga biome.
The fir tree is in the tundra biome,
and the cactus is in the rain forest
biome.

biome, and the cactus is in the
desert biome
The fir tree is in the grassland biome,
and the cactus is in the coniferous
forest biome
Which area do NOT support saltwater or marine aquatic life zones?
estuaries
coastal wetlands
shorelines
inland wetlands
The soil in a temperate forest biome is very
fertile. Which feature of this biome causes fertile
soil?
The warm summers dry out the soil, which
increases the concentration of nutrients
The leaves fall off the trees each year and
decay, which provides nutrients to the soil.
The dry climate is ideal for weathering rocks and
other materials, and this creates more soil.
The animals hibernate each winter, and the soil
can make more nutrients without animals.
How does the aquatic sand flat provide an
environment that supports the cowtail stingray in the picture above?
It has a lot of light with which the stingray can
make energy.

sand.
It has low levels of oxygen for the stingray to
breathe.
The picture shows a tropical rain forest with a
large tree canopy that lets through very little
sunlight.
Which of the following is a form of life that
survives well in this environment?
fungi that enjoy the dark forest floor and help to
get rid of animal and plant waste
mammals that need the dark, moist soil of the
forest floor in which to lay their eggs
plants that use moonlight to make food and
energy for growth
insects that require no water because rainfall is
blocked by the canopy
What would you expect to happen to vegetation as latitude and/or altitude increases?
