1. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem?

2. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem? Ecosystem a system involving the interactions between a community of living organisms in a particular area and its nonliving environment

3. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem? Limiting Factors anything that restricts the number of individuals in a population. They are biotic and abiotic factors

4. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem? Biotic Factors Living parts of the environment -animals -plants -bacteria

5. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem? Abiotic Factors Non-living parts of the environment - sunlight - air -water -temperature - space

6. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem? Competition occurs whenever more than one individual or population tries to make use of the same resource

7. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem? Intraspecific competition members of the same species compete for the same resources

8. Topic: Limiting Factors Essential Question: What do organisms depend on and compete for in an ecosystem? Interspecific competition When different species compete for resources

9. ENVIRONMENT ORGANIZATION INDIVIDUAL – One organism of a species. POPULATION- All of the organisms of the same species that live in the same area. COMMUNITY- All of the living organisms that live in the same area. ECOSYSTEM- All of the living organisms and nonliving factors in the same area. BIOSPHERE- Anywhere life is found on the planet.

10. INDIVIDUAL POPULATION COMMUNITY ECOSYSTEM BIOSPHERE

11. BIOTIC FACTORS- The living or once living factors in an ecosystem. Ex. human, hawk, plants, fish, turtle

12. ABIOTIC FACTORS- All of the nonliving factors in an ecosystem. Ex. land, water, air, temperature, rocks, sunlight

13. HABITAT - The place where an organism lives.

14. NICHE - The role an organism has in its ecosystem.
