Biomes

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)
