Unit 1-1 NotesMr. Hefti – Pulaski Biology

Living v. Non-living

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.

Living Non-living

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

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

Lichen (5)

Is a fossil (6) alive?

These substances can be found in living things… does that mean they are living?

NaCl (7)

Iron (8)

Water (9)

What about the rocks (10)? The crayfish (11)?Pollutants (12)? Insects (13)? Moss (14)? Sunlight (15)?

???

Honeybee (16)

Honey (17)

What about viruses (18)?

Is it dead or alive? Living or non-living?

Stump (19)

Dirt (20)

Carcass (Free)

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

Biotic / Abiotic

• Biotic: living, once living, or from something livingExamples:

- Plants- Animals- Dead leaves- Bacteria- Scat (animal droppings)

• Abiotic: non-living and never was living Examples:

- Oxygen- Wind- Minerals- pH- Water- Rocks

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…
