Name two types of biogeochemical cycles ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Biogeochemical Cycles**: Biogeochemical cycles are natural processes that recycle nutrients in various chemical forms from the environment to organisms and then back to the environment. They are essential for maintaining the balance of ecosystems.

2. **Identifying Types of Biogeochemical Cycles**: There are two main types of biogeochemical cycles:
- **Sedimentary Cycle**: This cycle involves the movement of nutrients that are primarily found in the earth's crust and sediments. The reservoir for these nutrients is solid or sedimentary in nature. An example of a sedimentary cycle is the **Phosphorus Cycle**.
- **Gaseous Cycle**: This cycle involves the movement of nutrients that are found in the atmosphere. The reservoir for these nutrients is gaseous. Examples of gaseous cycles include the **Carbon Cycle**, **Nitrogen Cycle**, and **Sulfur Cycle**.
