Understanding the Task

We are given a diagram of a pond ecosystem. The goal is to identify:

- Biotic factors: These are the living components of the ecosystem.
- Abiotic factors: These are the non-living components of the ecosystem.

---

Step 1: Identify Biotic Factors (Living Things)

Look at the living organisms in the picture:

1. Frog
2. Tadpoles
3. Flies
4. Fish
5. Snail
6. Water weeds (plants)

✔ These are all living things, so they are biotic factors.

---

Step 2: Identify Abiotic Factors (Non-Living Components)

Now look at the non-living parts of the environment:

1. Sun – provides light and energy
2. Air – atmosphere, needed for breathing
3. Water – habitat for aquatic life
4. Soil – supports plants and provides nutrients
5. Log (wood) – part of the physical environment (dead wood)

✔ These are abiotic factors.

> Note: The log is abiotic because it’s dead organic matter now, not alive.

---

✔ Final Answer:

#### Biotic Factors:
1. Frog
2. Tadpoles
3. Flies
4. Fish
5. Snail
6. Water weeds

#### Abiotic Factors:
1. Sun
2. Air
3. Water
4. Soil
5. Log (or Wood)

💡 Explanation:

- Biotic = Living things → animals, plants, insects.
- Abiotic = Non-living things → sunlight, air, water, soil, temperature, etc.

These factors interact to form a balanced ecosystem. For example:
- The sun provides energy for water weeds (photosynthesis).
- Frogs eat flies and tadpoles, showing food chain relationships.
- Water and soil support plant and animal life.

✔ Completed Worksheet Answer:

Biotic factors
- Frog
- Tadpoles
- Flies
- Fish
- Snail
- Water weeds

Abiotic factors
- Sun
- Air
- Water
- Soil
- Log (or Wood)
