Let's solve this Abiotic vs Biotic Factors Worksheet step by step and explain the answers clearly.

---

1. The root word BIO means life. What is a BIOTIC factor?

✔ Answer: A biotic factor is any living component of an ecosystem. These include plants, animals, fungi, bacteria, and other organisms that affect the environment and each other.

> 🔍 *Explanation:* Since "bio" means life, biotic factors are things that are alive or were once alive and influence the ecosystem.

---

2. The root “A-“ means not. What is an ABIOTIC factor?

✔ Answer: An abiotic factor is any non-living component of an ecosystem. These include physical and chemical elements like temperature, water, sunlight, soil, air, etc.

> 🔍 *Explanation:* "A-" means "not," so abiotic means "not living." These are environmental conditions that affect living organisms but are not alive themselves.

Label the following items as A for Abiotic or B for Biotic:

| # | Item | Answer | Explanation |
|---|--------------------|--------|-----------|
| 1. | Wind | A | Wind is moving air — non-living |
| 2. | Temperature | A | Physical condition — non-living |
| 3. | Water | A | Non-living substance |
| 4. | Fish | B | Living organism |
| 5. | Sunlight | A | Energy from the sun — non-living |
| 6. | Glass (lightning) | A | Lightning is electrical discharge — non-living |
| 7. | Iron | A | Chemical element — non-living |
| 8. | Carbon dioxide | A | Gas in atmosphere — non-living |
| 9. | Sand | A | Made of minerals — non-living |
|10. | Clouds | A | Made of water vapor — non-living |
|11. | Snail | B | Living animal |
|12. | Mold | B | Fungus — living organism |
|13. | Fire | A | Combustion — non-living process |
|14. | Venus Fly Trap | B | Plant — living organism |
|15. | Rock | A | Mineral formation — non-living |
|16. | Tornado | A | Weather event — non-living |
|17. | Gold | A | Element — non-living |
|18. | Sun | A | Star — non-living (though it supports life) |
|19. | Grapes | B | Fruit from plant — part of a living organism |
|20. | Air | A | Mixture of gases — non-living |

List the abiotic and biotic factors in the below image.

We are given a black-and-white drawing showing:
- A lake
- Trees and shrubs on land and in water
- A bird flying
- A person fishing in a boat
- A house in the background
- Rocks and grass
- Fish in the water

Now, identify four abiotic and four biotic factors.

#### ✔ Abiotic Factors List 4
These are non-living components:

1. Water – The lake and river
2. Sunlight – Shining on the scene (implied)
3. Air – Atmosphere where bird flies
4. Soil/Rock – Land and bank material

> 🌿 *Note:* You can also list temperature, wind, or sand, but based on visual cues, water, sunlight, air, and soil/rock are most evident.

#### ✔ Biotic Factors List 4
These are living components:

1. Fish – Swimming in the water
2. Bird – Flying above the lake
3. Trees/Plants – On shore and in water
4. Human (fisherman) – Person in the boat

> 🐟 *Note:* The Venus flytrap was listed earlier, but it’s not in this image. Here, we use what’s visible.

✔ Final Answer Summary:

#### Part 1: Definitions
1. Biotic factor: A living thing in an ecosystem (e.g., plants, animals).
2. Abiotic factor: A non-living thing in an ecosystem (e.g., water, temperature).

#### Part 2: Labeling (A = Abiotic, B = Biotic)

| # | Item | Answer |
|---|-----------------------|--------|
| 1. | Wind | A |
| 2. | Temperature | A |
| 3. | Water | A |
| 4. | Fish | B |
| 5. | Sunlight | A |
| 6. | Glass (lightning) | A |
| 7. | Iron | A |
| 8. | Carbon dioxide | A |
| 9. | Sand | A |
|10. | Clouds | A |
|11. | Snail | B |
|12. | Mold | B |
|13. | Fire | A |
|14. | Venus Fly Trap | B |
|15. | Rock | A |
|16. | Tornado | A |
|17. | Gold | A |
|18. | Sun | A |
|19. | Grapes | B |
|20. | Air | A |

#### Part 3: Image Analysis

| Abiotic Factors List 4 | Biotic Factors List 4 |
|------------------------|------------------------|
| 1. Water | 1. Fish |
| 2. Sunlight | 2. Bird |
| 3. Air | 3. Trees/Plants |
| 4. Soil/Rock | 4. Human (fisherman) |

✔ Conclusion: This worksheet helps students distinguish between living (biotic) and non-living (abiotic) components of ecosystems. The key is understanding that biotic = life, and abiotic = not life, even if they interact closely.
