All About Land Biomes Biome: A geographic area on Earth that contains ecosystems with similar biotic and abiotic features.

a biome that receive very little rain. Desert Biome: a biome that receive very little rain.

Desert Biome Earths driest ecosystem. Most deserts are hot during the day and cold during the night. (Others like Antarctica remains cold all of the time) Rainwater drains away quickly because of thin, porous soil.

Desert Abiotic Factors Receives less than 10 inches (25 cm) of rain per year. The average daytime temperature is 100°F (38°C) while at night the average temperature is 25°F (-4°C). This large temperature difference is due to low amount of moisture in the desert air.

Grassland Biome: Areas where grasses are the dominate plants.

Grassland Biome Also called “prairies”, “savannas” and “meadows” Have wet and dry seasons Trees grow along moist banks of streams and rivers. Wildflowers bloom during wet seasons

Grassland Biome Animals and Plants (Biotic Factors) Elk Rabbits Prairie dogs Hawks Coyotes African savannas contain – giraffes, zebras and lions. Wildflowers Worlds “Breadbasket” (wheat, corn, oats, rye, barley) Wild oats foxtail buffalo grass

Grassland Abiotic Factors There is an average of 19 – 36 inches (50-90 cm) of rainfall a year. The average temperature ranges from -4°F to 86°F (-20°C to 30°C) per year. Grasslands are generally open and continuous, fairly flat areas of grass. The soil is porous, with rapid drainage of water.

Tropical Rainforest Biome: The forest that grows near the equator.

Tropical Rainforest Biome Forests that receive large amount of rain Has dense growth of tall, leafy trees. Weather is warm and wet year-round. Half of Earths species live in tropical rainforest.

Tropical Rainforest: Abiotic Factors Soil is shallow and easily washed away by rain Less than 1% of sunlight that reach the top of the forest trees also reach the forest floor. Yearly temperature is between 68 °F (20 °C) and 93 °F (34 °C) Rainfall is often more than 100 inches (254 cm) a year.

Temperate Rainforest Biome: Regions of Earth between the tropics and the polar circles.

Temperate Rainforest Biome Temperate means “not too extreme” Moist ecosystems mostly in coastal areas. Not as warm as tropical rainforests. Winters are mild and rainy. Summers are cool and foggy.

Temperate Rainforest: Abiotic Factors Soil is rich and moist. The temperature is generally between -20°F and 90°F (-29°C and 30°C) There is lots of rain throughout the year, usually between 30 and 60 inches (76-152 cm) of rain.

Temperate Deciduous Forest Biome: Dominated by trees that lose their leaves each year.

Temperate Deciduous Forest Biome These forests are the most common forest ecosystems in the United States. Winter temperatures are often below freezing. Snow is common. Summers are hot and humid.

Temperate Deciduous Forest: Abiotic Factors Soil is rich in nutrients and supports a large amount of diverse plant growth. The average temperature of the forest is about 50°F (10° C). The average amount of rainfall in the forest is 30 to 60 (76 – 152 cm) inches a year. As the seasons change, so do the colors of the leaves of the deciduous.

Taiga Biome: A forest biome consisting mostly of conebearing evergreen tree.

Taiga Biome Exist only in the northern hemisphere. Winters are long, cold and snowy. Summers are short, warm and moist.

Tiaga Biome: Abiotic Factors Soil is thin and acidic. The average temperature per year is between 26°F-50 (-3°C- 10°C). The totally yearly precipitation is between 12 - 33 inches (30 - 85 cm).

Tundra Biome: Cold, dry and treeless.

Tundra Biome Most tundra's are south of the north pole, but also exist in mountainous areas at high altitudes. Winters are long, dark and freezing Summers are short and cool

Tundra Biome Animals and Plants (Biotic Factors) Shallow-rooted mosses and grasses Lichens Lemmings Water birds Polar bears Arctic fox White wolves

Tundra Biome: Abiotic Factors Permafrost- a layer of permanently frozen soil which prevents deep root growth. The average winter temperature is -30° F (-34° C), but the average summer temperature is 37-54° F (3-12° C ). Yearly precipitation, including melting snow, is 6 to 10 inches (15 to 25 cm).
