Which of the following sets explains the abiotic components in a pond ecosystem ?

Options

A. Water with dissolved inorganic substances
B. Water with dissolved inorganic and organic substances
C. Water with dissolved inorganic and organic substances and also the soil at the bottom
D. Water without any dissolved substances .

Answer

To determine which set explains the abiotic components in a pond ecosystem, we need to understand what abiotic components are. Abiotic components refer to the non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. In a pond ecosystem, these components include water, minerals, soil, and other inorganic and organic substances.

### Step-by-Step Solution:

1. **Identify Abiotic Components**:
- Abiotic components in a pond ecosystem include water, dissolved inorganic substances (like minerals), organic substances (like decomposed matter), and soil.

2. **Analyze the Options**:
- **Option 1**: Water with dissolved inorganic substances.
- This includes water and minerals but lacks organic substances and soil.
- **Option 2**: Water with dissolved inorganic and organic substances.
- This includes both inorganic and organic components but does not mention soil.
- **Option 3**: Water with dissolved inorganic and organic substances and also soil at the bottom.
- This option includes all the necessary abiotic components: water, inorganic substances, organic substances, and soil.
- **Option 4**: Water without any dissolved substances.
- This option does not include any abiotic components as it lacks both inorganic and organic substances.

3. **Select the Correct Option**:
- The most comprehensive option that includes all the abiotic components of a pond ecosystem is **Option 3**: water with dissolved inorganic and organic substances and also soil at the bottom.

### Final Answer:
The correct set that explains the abiotic components in a pond ecosystem is **Option 3**.
