Biomes

Review

Levels of Ecological Organization• Organisms make up a population.• Populations make up a Biological

community. • Communities and the nonliving factors

make up an ecosystem.• Ecosystems make up a biome.• Biomes make up the biosphere.

Biome

• A large group of ecosystems that share the same climate and have similar types of communities.

BiomesBiomes are determined by:

1) climate

2) Plant species

3) Animal species

CLIMATE

• The average weather conditions including TEMPERATURE and PRECIPITATION.

• What’s weather?? The condition of the atmosphere at a specific place and time.

There are Nine major biomes

1. Rain forest

2. Desert

3. Temperate Grassland

4. Tropical seasonal forest

5. Boreal Forest

6. Tundra

7. Temperate Forest

8. Temperate Woodland

9. Savanna

These are the ones in the book So that’s what we're going with!

BRAIN POP

RAIN FOREST• There are two

types of rain forest.

TROPICAL &

TEMPERATE

RAIN FOREST• A tropical rain forest’s

climate does not vary much throughout the year.

• It will have warm temperatures year round with lots of sunshine.

• It also will have up to 400 cm. of rainfall in a year.

• The world’s rain forest are located along the equator.

RAIN FOREST• The largest variety of

species is also found in the tropical rainforest.

• The distinct layers of the rain forest provide for abundant plant life and habitats for many animals.

RAIN FOREST• Temperate rain forest

are similar to tropical in that they receive up to 300 cm. of rainfall a year.

• However it is too far north to have the warm year round temperatures.

• They are located on the Northwestern coast of the United States.

Desert• This biome has

extreme temperatures. Hot in the day and cool to cold at night.

• It receives less than 25 cm. of rainfall in a year. And some years may receive none.

Desert• There is little

vegetation in the desert biome due to the high evaporation level.

• The organisms that live in the desert are adapted to the lack of rain and extreme temperatures.

Grasslands• Grasslands receive about

25 to 75 cm of rain each year.

• Typically they are populated by grasses and other non-woody plants.

• Prairies are located in the middle latitudes while savannas are located closer to the equator

Grasslands• Grasslands are home

to many of the largest animals on earth

bison

antelopes

zebras

rhinoceros

giraffes

kangaroos

Deciduous Forest• The temperatures in a

deciduous forest will vary throughout the year with warm summers and cold winters.

• This biome will receive at least 50 cm of precipitation each year.

Deciduous Forest• The trees in this forest

are deciduous, that is they shed their leaves and grow new ones each year.

• There are a number of animal species in this biome, however during the winter some birds will migrate and other animals will hibernate.

Boreal Forest• Boreal forest are also

referred to as the taiga biome.

• It is characterized by a cold, harsh climate with low rate of precipitation.

• The forests contain mostly coniferous trees.

Boreal Forest• This biome span the

northern part of North America, Europe, and Asia.

• The Boreal forest is the largest biome on earth.

• Its animal diversity is somewhat limited due to the harsh winters.

Tundra• The tundra is

extremely cold and dry.

• It is the coldest biome with very little vegetation. Mostly mosses, grasses, and a few small shrubs.

• There is very little precipitation.

Tundra• Most of the soil in the tundra called

permafrost, is frozen all year.• The animals in this area grow thick

fur coats to survive the winters.

Water Biomes• There are two water

biomes.

FRESHWATER

& SALTWATER• These biomes are

affected by temperature, sunlight, oxygen, and salt content.

Freshwater biomes• Ponds and Lakes which are bodies of

standing, or still freshwater.• Streams and Rivers which are bodies of

more rapid moving freshwater.• Estuaries which is the shallow sunlit water

where the river meets the salt water of the ocean.

Salt water biomes• This biome is also referred to as a marine

biome.• Marine biomes vary according to the

amount of sunlight, degree of water temperature, and amount of water movement.

• There is also a wide variation of animal life throughout the different levels.
