Which biome has sandy, rocky soil?
The desert
Which two biomes are the most similar?
Taiga and Tundra
Which biome has trees with leaves that change
color in the fall.
Which biome has trees that change color
the fall?
What is a biome?
One of earth’s major land ecosystems with its
own characteristics, animals, plants, soil and
climate.
Name the 7 terrestrial biomes.
Desert, tundra, taiga, tropical rain forest,
temperate rain forest, grassland and deciduous
forest
What is the continuous movement of water
between Earth’s surface and the air called..
Water cycle
In this cycle nitrogen must be fixed in order for
plants to use it
Nitrogen Cycle
The continuous exchange of carbon among
living things is called
The Carbon Cycle
Would removing animals from the carbon cycle
stop the cycle? Explain:
No, the cycle could keep going. Animals add to
the carbon , but they are not needed to sustain
it.
What would happen to the carbon cycle if all
decomposers on earth suddenly died?
Large amounts of carbon would be stored in the
tissues of dead plants and animals would not be
available for use by other living things.
If a species cannot adapt to changes in an
ecosystem it may become..
extinct
If an animal is extinct can we bring it back under
the right conditions?
No
If a plant has leaves and branches that store
water in which biome could this plant be found?
desert
If an animals has thick coats, layers of fat,
hibernation during the winter as adaptations. In
which biome would it be found.
taiga
If there is an increase in the number of rabbits
in a population then how could this change an
ecosystem.
A decrease in the producers (plants), and
increase in the secondary consumers etc..
Leading to a disruption in the balance of an
ecosystem.
Animals that are active only at night and
burrow underground to stay cool
In which biome would you find this animals?
desert
Animals have thick fur, layers of fat, migration,
plants have shallow roots, adapted to short
growing season.
Tundra
Flowers bloom, ice melts, insects breed,
migrating birds move into the area
Which biome?
Taiga
Monkey, bats, toucans, tree frogs, snakes,
insects
In which biome can ALL of these be found? Taiga
Tropical Rain Forest
In this biome you could find hardwood trees, 4
distinct seasons.
Deciduous Forest
Does the Earth have the same amounts of fresh
and salt water?
No, there is 97% salt water
Fresh water is 3%
In which biome do you live?
Deciduous Forest
Fish, snakes, whales are found in these
Water ecosystems
This is where salt water and fresh water meet
Estuary
Why are most plants in a water ecosystem
found in the shallow water?
Because plants need sunlight for photosynthesis
Many people want to live near
water. As a result, many homes are
being built very close to the shores
of larger lakes. How might
construction of these homes affect
the lake ecosystem?
If homes are built close to the waters
edge, many of the larger organisms in
the shallow water zone, such as frogs,
birds, turtles, and other small
predators, might have their habitat
polluted or destroyed and die or leave.
The ecosystem would be out of balance.
