• See if you can list, from memory, the 6 characteristics that are necessary for a factor to be considered “biotic”.
Biomes and Ecosystems
What is a biome? A biome is a large geographical region
characterized by a specific climate and distinct types of plants and animals
What is a biome? Sometimes people use the words
“ecosystem” and “biome” interchangeably, meaning they can mean the same thing
However, technically an ecosystem can be much smaller than a biome (it can be as small as a puddle!)
Let’s Review the Major Biomes
• Temperate Deciduous Forests
Yearly Rainfall: 30-49 inches
Average Temperatures: 43 to 82 degrees Fahrenheit
Animals: rabbits, deer, squirrels, bears, lots of birds
Plants: deciduous trees (leaves fall off in the autumn), grass, ferns, woody shrubs
Let’s Review the Major Biomes
• Coniferous Forests
Yearly Rainfall: 14 -30 inches
Average Temperature: 14 – 57 degrees Fahrenheit
Animals: moose, deer, chipmunks, foxes, birds
Plants: evergreen trees (they never lose their leaves and often have needles, like pine trees)
Let’s Review the Major Biomes
• Tropical Rain Forests
Yearly Rainfall: up to 158 inches
Average Temperatures: 68 – 93 degrees Fahrenheit
Plants: hundreds and hundreds of different types (most diversity in the world)
Animals: monkeys, parrots, butterflies, snakes and MANY more!

• Temperate Grasslands
Yearly Rainfall: 10 – 30 inches
Average Temperatures: 32 – 86 degrees Fahrenheit
Plants: grass, some flowers
Animals: prairie dogs, mice, bison

Deserts
Yearly Rainfall: less than 10 inches
Average Temperatures: 45 – 100 degrees Fahrenheit
Plants: cacti, some flowers, some bushes
Animals: jack rabbits, rats, lizards, snakes
Let’s Review the Major Biomes
• Tundra Yearly Rainfall: 12-20 inches
Average Temperatures: -14 to 54 degrees Fahrenheit
Plants: ground covered in permafrost and only the surface thaws in the summer so only grass and some shrubs grow
Animals: caribou, wolves, lemmings, hares
