Reservoir of gaseous cycle is

Options

A. stratosphere
B. atmosphere
C. ionosphere
D. lithosphere

Answer

**Step-by-Step Solution:**

1. **Understanding Gaseous Cycles**: Begin by recognizing that gaseous cycles refer to the movement and exchange of gases within an ecosystem. Important examples include the carbon cycle, nitrogen cycle, and oxygen cycle.

2. **Identifying the Reservoir**: In the context of gaseous cycles, a reservoir is a storage location for gases. For these cycles, the primary reservoir is the atmosphere.

3. **Components of the Atmosphere**: The atmosphere consists of various layers, including the troposphere, stratosphere, and ionosphere. These layers contain different gases that are crucial for life on Earth.

4. **Function of the Atmosphere**: The atmosphere plays a vital role in supporting life by providing essential gases like oxygen and carbon dioxide, which are involved in various biological processes.

5. **Conclusion**: Therefore, the reservoir of the gaseous cycle is the atmosphere, as it contains and regulates the gases necessary for life.
