• Habitat = The area inhabited by a particular species
Biotic and Abiotic Factors
• Biotic factors = All the living organisms that are part of an environment
Biotic and Abiotic Factors
• Biotic factors = All the living organisms that are part of an environment
• Abiotic factors = Non-living chemical and physical factors in the environment (for example: temperature, light, water, and nutrients)
Output activity (pg 5)
• Make 2 columns, labeled “biotic” and “abiotic”
• List at least 5 biotic and 5 abiotic factors that affect you daily
Limiting factors (pg 4)
• Limiting factor = The biotic or abiotic factor that limits the survival and productivity of an organism
• Limiting factor = The biotic or abiotic factor that limits the survival and productivity of an organism
• Example: Limiting factors for plantsIn the desert = WaterIn the rainforest = Light or herbivores
