1. Biomes Biology Capital H. S.

2. Limiting Factors Prevent population from reaching biotic potential Types –Density dependent –Density independent

3. Limiting Factors Density dependent Effect becomes more intense with increased density Examples –Parasites & diseases –Competition for resources –Toxic effect of waste products –Predation

4. Limiting Factors Density independent Occur independently of density Examples: –Natural disasters –Climate extremes

5. Biomes Large group of ecosystems that share the same type of climax community. Based on climate: –Light –Water –Temperature

6. Types of Biomes Terrestrial (land) Aquatic (water)

8. Tropical Rainforest Tall trees High temperature Heavy rainfall

9. Which Biome is it?

10. Desert Cactus/succulents Hot days, cold nights Hot summers Little rain

11. Which Biome is it? http://66.9.79.220/images/Savanna.jpg

12. Which Biome is it? Savannas –Tropical –Scattered trees –High temperature –Less rainfall than tropical rain forest

13. Grasslands Temperate –Grasses –Seasonal droughts –Occasional fires –Lower temperature & less rainfall than savannas
