16. Identify the level of the following:

17. With a partner, identify the following:
1. Biotic factor
3. Organism
5. Community
2. Abiotic factor
4. Population
6. Level of Organization
Biotic Factor – any of the living things; Abiotic Factor – water, soil, sun/temperature/weather, etc; Organism – any of the living things; Population – really the bear is the only organism that I can see has more than one but students might say other organisms if they can explain that it would need to be more than one; Community – any combination of living organisms; Level of Organization - Ecosystem
