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

Plants in Tundra
 Lichens
 Mosses
 Small shrubs

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 Animals
 Average 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 tundra
 It can affect the feeling patterns of the
animals
 It can affect animal and bird migration

How to Reduce Negative
Impact of Humans
 Create environmental awareness of
ecosystems and pollution
 Have strict government regulations
 Minimize disturbances on ecosystems
