Biomes Cycles IF Adaptations Grab Bag

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 colorthe 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.
