Study Notes
Rainfall and Temperature Patterns in Biomes
- Tundra and Desert receive the same amount of rainfall.
- Tropical rainforest has the highest rainfall among North American biomes.
- Desert has the highest average temperature of all biomes.
- Tundra and grasslands exhibit similar average temperatures.
Types of Forests
- Coniferous forest is also known as Taiga.
- Three forest types include Coniferous forest (Taiga), Temperate deciduous forest, and Tropical rainforest.
Climate Characteristics
- The primary differentiator between tundra and desert is the average temperature.
- Tundra is referred to as the "frozen desert" due to minimal precipitation and an average temperature of -10°C.
Grasslands vs. Forests
- The difference between grasslands and temperate deciduous forests lies in average precipitation levels.
- Grasslands support grasses over trees due to insufficient rainfall.
Relationship Between Climate and Forest Size
- Larger trees grow in regions with more rainfall, establishing a connection between temperature, rainfall, and forest size.
Biomes Representation
- Model 2 uses an x-axis to show trends in the number of species and a y-axis to denote distance from the equator (latitudinal regions).
- The distance from the equator correlates with temperature variations.
Biomes and Species Diversity
- Six biomes include Tundra, Taiga, Desert, Grasslands, Temperate deciduous forest, and Tropical rainforest.
- The Arctic region displays the fewest species, while the Tropical rainforest boasts the highest biodiversity.
Biodiversity in Biomes
- Tropical rainforest supports diverse species due to ample rainfall and rich plant life.
- Tundra has the lowest biodiversity, hampered by low rainfall, limited plant life, and extreme cold.
Biodiversity Trends
- Biodiversity tends to increase as latitude decreases, moving from the Arctic towards the equator.
Importance of Grasslands
- Grasslands serve as the "bread basket" for agriculture (grain farming) and animal farming in the U.S.
- Climate change may result in decreased rainfall and increased temperatures in grasslands, impacting food production capacities.
