Sort biotic and abiotic factors in this interactive worksheet.

To solve this, we need to sort each item into either Biotic Factors (living or once-living things) or Abiotic Factors (non-living physical and chemical parts of the environment).

Let’s go through each item one by one:

---

Biotic Factors = living organisms or things that were once alive (like dead bugs, rotting logs)

- A dead bug → was once alive → Biotic
- A rotting log → was part of a tree (alive) → Biotic
- A vulture → animal, alive → Biotic
- Elephants → animals → Biotic
- Flowers → plants → Biotic
- Grass → plant → Biotic
- Humans → animals → Biotic
- Platypus → animal → Biotic
- Seaweed → plant-like organism → Biotic
- Spider → animal → Biotic
- Termite → insect → Biotic
- Weeds → plants → Biotic

That’s 12 biotic items.

Abiotic Factors = non-living things like air, water, rocks, sunlight, climate, etc.

- Air → gas mixture → Abiotic
- Carbon dioxide → gas → Abiotic
- Climate → weather patterns over time → Abiotic
- Diamonds → mineral → Abiotic
- Dirt → soil (mix of minerals, but not living itself) → Abiotic
- Humidity → amount of water vapor in air → Abiotic
- Mountains → landform → Abiotic
- Oxygen → gas → Abiotic
- Precipitation → rain/snow → Abiotic
- Rocks → mineral → Abiotic
- Sunlight → energy from sun → Abiotic
- Water → liquid → Abiotic

That’s 12 abiotic items.

Wait — let’s double-check the list given in the image to make sure we didn’t miss any or miscount.

Original list (from image):

Left column:
- A dead bug
- A rotting log
- A vulture
- Air
- Carbon dioxide
- Climate

Middle-left:
- Diamonds
- Dirt
- Elephants
- Flowers
- Grass
- Humans

Middle-right:
- Humidity
- Mountains
- Oxygen
- Platypus
- Precipitation
- Rocks

Right column:
- Seaweed
- Spider
- Sunlight
- Termite
- Water
- Weeds

Total: 24 items → should be 12 biotic, 12 abiotic.

Now re-sort carefully:

✔ Biotic (living or once-living):
1. A dead bug
2. A rotting log
3. A vulture
4. Elephants
5. Flowers
6. Grass
7. Humans
8. Platypus
9. Seaweed
10. Spider
11. Termite
12. Weeds

✔ Abiotic (non-living):
1. Air
2. Carbon dioxide
3. Climate
4. Diamonds
5. Dirt
6. Humidity
7. Mountains
8. Oxygen
9. Precipitation
10. Rocks
11. Sunlight
12. Water

Perfect — 12 each.

Note: “Dirt” is sometimes tricky — it contains organic matter, but as a factor, it’s considered abiotic because it’s the physical medium, not the living thing itself. Similarly, “a rotting log” is biotic because it was once part of a living tree.

Final Answer:

Biotic Factors:
A dead bug
A rotting log
A vulture
Elephants
Flowers
Grass
Humans
Platypus
Seaweed
Spider
Termite
Weeds

Abiotic Factors:
Air
Carbon dioxide
Climate
Diamonds
Dirt
Humidity
Mountains
Oxygen
Precipitation
Rocks
Sunlight
Water
