1. Unit 1-1 Notes Mr. Hefti – Pulaski Biology Living v. Non-living

2. Please make a t-chart that is about half a page in size in your notes and list the living and non-living things you are about to see in the appropriate columns. LivingNon-living

3. Are bones (1) living? What about algae (2)?

4. Garbage(3)? Freshly cut tree(4)?

5. Lichen (5)

6. Is a fossil (6) alive?

13. 8 Characteristics of Life Biologists characterize life by these functions: – Nutrition – Transport – Respiration – Excretion – Synthesis – Regulation – Growth – Reproduction

14. Biotic / Abiotic Biotic: living, once living, or from something living Examples: - Plants - Animals - Dead leaves - Bacteria - Scat (animal droppings)

15. Abiotic: non-living and never was living Examples: - Oxygen - Wind - Minerals - pH - Water - Rocks

16. Please make a t-chart in your notes (this time a quarter of a page) and list the biotic and abiotic factors in the following picture of a rotting log ecosystem. Use your imagination to identify things that just might be there… BioticAbiotic
