1. Biomes Lecture

2. What is a biome?
A major type of ecosystem with distinctive temperature, rainfall, and organisms.

3. There are.. Terrestrial Biomes Aquatic Biomes
(75% of Earth’s surface is covered by water)

4. Aquatic Biomes
There are many aquatic biomes with different aspects. They may vary by….
Salinity of water (fresh vs. marine)
Depth vs. Light
Temperature
Dissolved Oxygen Levels
Much more…

5. Terrestrial Biomes Include:
Tundra
Treeless land with usually freezing temperatures.
Permafrost

6. Temperate Forest ~Hardwood trees ~4 definitive seasons
*mild-moderate winters
*warm summers

7. California’s short shrub community

8. Most biologically diverse
Tropical Rain Forest

9. Desert Very dry and little plant life.
Plants must reduce water loss with many types of adaptations.

10. Grassland
Large communities covered with grasses and similar small plants.
Not enough rain to support forests.
Temperate (Prairies, steppes) and Tropical (savanna)

The atmospheric conditions over a short period of time, like a day or week.
For example, today the weather is cloudy with a chance of rain and a high of 54.

13. What is climate?
Climate is the average atmospheric conditions over a longer period of time, like a year.
For example, the climate in Florida is much more humid than the climate in Arizona.

14. Controlled by… Latitude Altitude Proximity to Oceans and Mountains
Proportion of land to water
