Which of the following processes is not responsible for adding particulates to the atmosphere ?

Options

A. Photosynthesis
B. Combustion of fuels
C. Industrial processes
D. Agricultural processes

Explanation

To determine which of the following processes is not responsible for adding particulates to the atmosphere, we need to analyze each option provided. The processes typically associated with adding particulates include combustion, industrial activities, and agricultural practices. Let's break down the options step by step:

1. **Combustion of Fuels**:
- Combustion of fuels involves burning fossil fuels, which releases various particulates into the atmosphere, including ash, smoke, and other pollutants. This process contributes significantly to air pollution.
- **Conclusion**: This process adds particulates to the atmosphere.

2. **Industrial Processes**:
- Industrial processes often involve the release of harmful gases and particulates as a byproduct of manufacturing and other activities. These can include dust, fumes, and other pollutants that are emitted into the air.
- **Conclusion**: This process also adds particulates to the atmosphere.

3. **Agricultural Processes**:
- Agricultural activities, such as the burning of crop residues and the use of fertilizers, can release particulates into the atmosphere. This includes dust from plowing fields and smoke from burning.
- **Conclusion**: This process contributes to the addition of particulates to the atmosphere.

4. **Photosynthesis**:
- Photosynthesis is a biological process where plants convert carbon dioxide and sunlight into oxygen and glucose. This process occurs at the molecular level within plants and does not release particulates into the atmosphere.
- **Conclusion**: This process does not add particulates to the atmosphere.

Based on the analysis of each option, the process that is **not responsible for adding particulates to the atmosphere** is **Photosynthesis**.

### Final Answer:
**Photosynthesis** is the process that does not add particulates to the atmosphere.
