How Animals Adapt to Living in Tundra

Some hibernate in winter

Some have their babies in the summer

They have thick fur for the cold

They survive on other animals in the food chain

How Plants Adapt to Tundra

They are short and very tight together to protect them from the cold and wind harsh environment

They manage to get their energy from the sun

They use small amounts of energy

Abiotic Factors That Affect Plants and

AnimalsAverage rainfall is only about 10 inches

each year.

Winters are 10 months long and the temperatures can reach 50 degrees below 0 Celsius.

Summers are only about 6 weeks long and the maximum temperature is 10 degrees.

How Abiotic Factors Affect Plants and

Animals Plants and animals have to make

adaptations to adjust to the harsh tundra environment

The low rainfall, cold temperatures and poor soil make the plants grow very small

Also it can be very difficult for animals to find food

Human Activities That Affect Tundra

Drilling for oil and gas

Mining for minerals

New towns and roads

These can be good because oil exploration and mining can create jobs for people

Negative Impact of Human Activities

Pollution The affect on the ecosystem of the

tundraIt can affect the feeling patterns of

the animalsIt can affect animal and bird migration

How to Reduce Negative Impact of

HumansCreate environmental awareness of

ecosystems and pollution

Have strict government regulations

Minimize disturbances on ecosystems
