Abiotic or Biotic worksheet - Free Printable

I need to classify each item as either a Biotic Factor (B) or an Abiotic Factor (A).

Let me work through this step by step:

Understanding the difference:
- Biotic factors = living things or things that were once alive (plants, animals, fungi, bacteria, etc.)
- Abiotic factors = non-living things in the environment (water, sunlight, rocks, soil, temperature, etc.)

Going through each item:

1. Oak Tree - This is a living plant → B

2. Cheetah - This is a living animal → B

3. Water - This is a non-living substance → A

4. Sunlight - This is energy from the sun, not living → A

5. Whale - This is a living animal → B

6. Deer - This is a living animal → B

7. Soil - This is made of minerals and decomposed matter, but soil itself is considered non-living → A

8. Rocks - These are non-living → A

9. Mushroom - This is a fungus, which is a living organism → B

10. Rain - This is water falling from clouds, non-living → A

11. Bacteria - These are living microorganisms → B

12. Rose Bush - This is a living plant → B

Let me double-check my answers:
- Oak Tree: B ✓
- Cheetah: B ✓
- Water: A ✓
- Sunlight: A ✓
- Whale: B ✓
- Deer: B ✓
- Soil: A ✓
- Rocks: A ✓
- Mushroom: B ✓
- Rain: A ✓
- Bacteria: B ✓
- Rose Bush: B ✓

All classifications look correct!

Final Answer:
Oak Tree: B
Cheetah: B
Water: A
Sunlight: A
Whale: B
Deer: B
Soil: A
Rocks: A
Mushroom: B
Rain: A
Bacteria: B
Rose Bush: B
