1. Notes: Biotic and Abiotic Factors
(page 4)

2. Definitions
• Ecology = The study of interactions between
organisms and their environment

3. Definitions
• Ecology = The study of interactions between
organisms and their environment
• Environment = An organism’s surroundings,
including living and non-living factors

4. Definitions
• Ecology = The study of interactions between
organisms and their environment
• Environment = An organism’s surroundings,
including living and non-living factors
• Habitat = The area inhabited by a particular
species

5. Biotic and Abiotic Factors
• Biotic factors = All the living organisms that
are part of an environment

6. 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)

7. Output activity (pg 5)
• Make 2 columns, labeled “biotic” and
“abiotic”
• List at least 5 biotic and 5 abiotic factors that
affect you daily

8. Limiting factors (pg 4)
• Limiting factor = The biotic or abiotic factor
that limits the survival and productivity of an
organism

9. • Limiting factor = The biotic or abiotic factor
that limits the survival and productivity of an
organism
• Example: Limiting factors for plants
In the desert = Water
In the rainforest = Light or herbivores
