Which order is correct with respect to the biodiversity of species ?

Options

A. Fungi `gt` Algae`gt` Lichens `gt` Angiosperm
B. Angiosperm `gt` Fungi `gt` Algae `gt` Lichen
C. Fungi `gt` Angiosperm `gt` Algae `gt` Lichen
D. mosses `gt` Ferns `gt` Algae `gt` Lichens

Answer

To determine the correct order with respect to the biodiversity of species among fungi, algae, lichens, and angiosperms, we can analyze each group based on their characteristics and complexity. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Characteristics of Each Group
1. **Fungi**:
- Eukaryotic organisms.
- Non-photosynthetic (cannot produce their own food).
- Nutritional modes include saprotrophic (decomposers) and some are parasitic.

2. **Algae**:
- Photosynthetic organisms.
- Can be categorized into three types: green algae, red algae, and brown algae.
- Considered lower plants.

3. **Lichens**:
- A symbiotic association between fungi and algae.
- Known as pioneer species, indicating they can colonize barren environments.

4. **Angiosperms**:
- Also known as flowering plants.
- Represent higher plants in terms of complexity.
- Divided into two groups: dicots and monocots.

### Step 2: Rank the Organisms by Biodiversity
- **Angiosperms** are the most complex and diverse, being flowering plants.
- **Fungi** come next, as they have a wide variety of forms and ecological roles.
- **Algae** follow, as they are simpler photosynthetic organisms.
- **Lichens** are last, as they are a combination of fungi and algae but do not represent a separate group in terms of biodiversity.

### Step 3: Establish the Correct Order
Based on the analysis:
1. Angiosperms (highest biodiversity)
2. Fungi
3. Algae
4. Lichens (lowest biodiversity)

### Conclusion
The correct order with respect to the biodiversity of species is:
**Angiosperms > Fungi > Algae > Lichens.**

### Final Answer
The answer to the question is option **B**.
