The BiosphereThe BiosphereCopy the stuff in Blue.

BiosphereBiosphere• The portion of the Earth that holds life

• Includes all organisms and the environments they live in

• Biotic – all the living things in the environment

–Ex. Animals, Plants, Bacteria etc.

• Abiotic – all the non-living things in the environment

–Ex. Rocks, Air, Water, etc.

BiomesBiomes• The biosphere is broken up into large

areas called biomes

• Biome: A large group of ecosystems that share the same environmental factors

• Biomes are based on the climate and the biotic and abiotic factors present

There are 2 types of Biomes:

Aquatic: Terrestrial:

Water biomes Land Biomes

AQUATIC BIOMESAQUATIC BIOMES• There are 3 Aquatic Biomes

–Marine Biomes: saltwater/ ocean

–Estuaries : Mix of fresh and salt water

–Freshwater Biomes: Lakes, rivers, ponds and streams

Terrestrial BiomesTerrestrial Biomes- Tundra

- Taiga

- Desert

- Grassland

- Temperate Forest

- Rainforest

TundraTundra• A treeless land with very little sunlight• Polar Climate• Permafrost: constant ice and snow that

freezes the ground• Shallow rooted grasses and plants• Weasels, artic fox, penguins and polar bears

live in the Tundra.

TundraTundra

TaigaTaiga• Continental Climate

• Continuous belt of pine, fur and spruce trees

• Warmer and wetter than tundra

• Harsh winters

• More large species of animal are found in the taiga:

lynx, elk, weasel, red deer, moose

TaigaTaiga

DesertDesert• An arid (dry) region with very little plant life• Dry Climate• Rainfall is the major limiting factor• Coyotes, hawks, snakes, lizards • Tumbleweeds and cacti all live in the

desert.

DesertDesert

GrasslandGrassland• Large communities covered with rich soil,

grasses, and similar plants.

• Dry Climate = No forest

• Ideal for cereal grains: oats, rye and wheat

• Grazing animals live in the grassland- Bison, rabbits, deer, prairie dog

GrasslandGrassland

Temperate ForestTemperate Forest• Our biome

• Mild Climate

• Average rainfall and broad-leaved trees that lose their leaves annually

• Animals that live there are bears, squirrels, mice, deer and rabbits.

• Many birds live in the forests

Temperate ForestTemperate Forest

Tropical Rain ForestTropical Rain Forest• Tropical Climate• Warmer temperature• Lots of rain• Lush plant growth : Bamboo, orchids,

carnivorous plants• Home to more species of organisms than

any other biome on Earth• Monkeys, jaguars, large snakes and many

different insects live in the rainforest
