BiosphereBiosphere• The portion of the Earth that holds life
• Includes all organisms and the environments they live in
![Page 3: The Biosphere Copy the stuff in Blue.. Biosphere The portion of the Earth that holds life Includes all organisms and the environments they live in](https://reader035.vdocuments.site/reader035/viewer/2022062518/56649e905503460f94b94835/html5/thumbnails/3.jpg)
• 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

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.

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

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.

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

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

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
