Land Biomes
Complete chart of Land Ecosystems using pages 474-480 in your textbook. Your description of the biome should include:
1) How much rain does it get
2) Temperature ranges
3) 3 facts about the Biome
Forests
Temperate Deciduous
Forests
Coniferous Forests
Tropical Rain Forests
Rainfall: 75-125 cm
- Deciduous comes from the Latin word “to fall off”
Temperature:
Summer: 28 OC
Winter: 6OC
- Lose leaves in changes of seasons
- Contains several species of trees and animals (bears and woodpeckers)
Rainfall: 35-75 cm
- Do not change very much from summer to winter
Temperature:
Summer: 14 OC
Winter: -10OC
- Trees do not lose leaves. Most trees have needles and cones
Rainfall: up to 400 cm
-Biome has the most biological diversity
Temperature:
Summer: 34 OC
Winter: 20OC
- Top soil is very thing and poor with nutrients
- Many animals that live there will hibernate or migrate in harsh winters
- Little light reaches the ground, any plants that live on tropical rainforest are specially
adapted to survive with very little light.
Grasslands
Temperate Grasslands
Rainfall: 25-75 cm
- Vegetation is mainly grasses with flowering plants
Temperature:
Summer: 30 OC
Winter: 0OC
- Herbivores, prairie dogs, mice, and bison live there
Rainfall: 150 cm
Savanna
Temperature:
Summer: 34 OC
Winter: 16OC
- Few trees because fires prevent growth of slow growing plants
- Scattered clump of trees, dry seasons causes grasses to die back but deep rooted plants
remain
- Diverse group of herbivores
- Elephants, giraffes, zebras, gazelles, and wildebeests
Desert
Desert
Rainfall: less than 25 cm
- Biome that gets the least amount of rainfall.
Temperature:
Summer: 38 OC
Winter: 7OC
- Plants grow further apart to reduce competition for water and nutrients
- Plants and animals have special adaptations to survive with very little water
Tundra
Arctic Tundra
Alpine Tundra
Rainfall: 30-50 cm
- Short growing season
Temperature:
Summer: 12 OC
Winter: -26OC
- Has permafrost- frozen layer under top surface which prevents water draining
- grasses, sedges, rushes, small wooden shrubs common
Rainfall: 30-50 cm
- Found above the tree-line of very high mountains
Temperature:
Summer: 12 OC
Winter: -26OC
- Receives lots of sunlight and precipitation mostly in the form of snow
