Which of the following represent maximum number of species among global biodiversity

Options

A. Mosses and ferns
B. Algae
C. Lichens
D. Fungi

Answer

To determine which group represents the maximum number of species among global biodiversity, we need to analyze the options provided: mosses and ferns, algae, lichens, and fungi.

### Step-by-Step Solution:

1. **Understanding the Options**:
- **Mosses and Ferns**: These are non-flowering plants that reproduce via spores. They have a relatively lower number of species compared to other groups.
- **Algae**: This group includes a wide variety of photosynthetic organisms, but they still do not represent the highest diversity.
- **Lichens**: These are symbiotic associations between fungi and algae or cyanobacteria. While they are diverse, they are not as numerous as fungi.
- **Fungi**: This group is known for its vast diversity. Fungi are present in various environments and can be found in soil, decaying matter, and as symbionts with plants and animals.

2. **Analyzing Fungi**:
- Fungi are cosmopolitan, meaning they can be found in almost every habitat on Earth.
- They have a cryptic lifestyle, allowing them to thrive in various conditions, including extreme environments.
- Fungi can withstand high salinity, ionizing radiation, and even UV rays, which contributes to their widespread presence.

3. **Conclusion**:
- Based on the analysis, fungi represent the maximum number of species among the options provided. They are more diverse than mosses, ferns, algae, and lichens.

### Final Answer:
The group that represents the maximum number of species among global biodiversity is **fungi**.
