Biomes of Our World

Biomes of Our World

• Unit Review

2
Tundra

• Found in most northern climates of the Earth.
• Too cold for many plants or animals to survive
• Land is covered with snow most of the year
• Short summer, animals hibernate to survive the
  winter

Bears, reindeer, moose, and birds live in the
tundra Most common tundra plant is the lichen.

Aquatic

• Type of Aquatic Biomes
• Oceans
• Rivers
• Wetlands

4
Forests

• Three main types of Forests
• Rainforest
• Coniferous forest
• Deciduous forest

5
Grasslands

• Grassy, windy, semi-dry biome
• Nearly one-fourth of the Earth's land
• Other names Savannah, plains, prairies, pampas
• Small creatures such as grasshoppers and beetles
  to large animals like lions, giraffes and
  cheetahs

Grasses are the main form of plant life
6
Desert

• Hot, dry biomes there are also "cold" deserts
• As there is little rainfall,
  few types of plants exist. Some
  vegetation includes cactus and the Joshua tree
• Animals in the desert
  include marmots, prairie dogs and several
  varieties of snakes and lizards

Receives less than 25 centimeters of rain a year.
7
Rainforest

• Hot and wet for millions of years
• Average temperature year-round is 80 deg.
• Seasons do not change in the tropical rain forest
• Richest source of plant life on earth
• So many different kinds of plants there,
  scientists don't even know them all yet

Billions of animals, birds, and insects

8
Coniferous

• Has trees that reproduce by dropping cones
• Forest floor has little growth since the large
  trees block out sunlight
• Birds and other animals live in the trees. Larger
  animals live on the forest floor. Deer and bear
  make this area their home

Located just south of the Tundra biome.

Deciduous

• Consist of trees that do not bear cones, contain
  seeds that drop on the nearby forest floor
• Since they lose their leaves, sunlight can reach
  the ground and plants can grow
• Weather is moderate. The summers are warm and the
  winters are cool

Home to many animals Rainfall tends to be heavy

10
Oceans

• Covers over 70 of the earth's surface and are
  home to many types
  of fish, mammals, and plants
• Large salt-water bodies connected across the
  earth
• Divided into different zones based on sunlight,
  temp, water pressure, water movement.

Plants Kelp, phytoplankton Animals lobsters,
crabs, many types of fish, dolphins, whales

Fresh Water

• Fresh water of the earth is contained in lakes,
  ponds, rivers and streams.
• Lakes are large bodies of freshwater surrounded
  by land, while ponds are smaller bodies of water
  surrounded by land
• Plants waterlilies, cattails, algae, duckweed,
  mosses

Many animals live in rivers and lakes fish,
snakes, frogs, ducks

Wetlands

• Wetlands are marshy areas where there is much
  moisture in the soil. Wetlands are sometimes
  covered in water. Swamps, marshes, and bogs are
  some of the names used for wetlands.
• Climate varies on the location of the specific
  wetland.

Waterfowl, fish, shellfish, many types of
wildlife. Many animals and plants depend on
wetlands for survival
