Options

A. iv,ii,I,iii,
B. iv,iii,I,ii
C. I,iii,ii,iv
D. iv,ii,iii,i

Explanation

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find its corresponding match in Column II.

### Step-by-Step Solution:

1. **Identify the first item in Column I: "Bacteria"**
- Bacteria are known to consume organic matter, which classifies them as micro-consumers.
- **Match:** Bacteria → (iv) Micro-consumers

2. **Identify the second item in Column I: "Green plants"**
- Green plants are known as transducers because they convert sunlight into energy through photosynthesis, making them producers in the food chain.
- **Match:** Green plants → (ii) Transducers

3. **Identify the third item in Column I: "Primary succession"**
- Primary succession refers to the process of ecological succession that occurs in an environment that has not been previously inhabited, often referred to as "prisere."
- **Match:** Primary succession → (i) Prisere

4. **Identify the fourth item in Column I: "Succession on bare rock"**
- This type of succession is specifically called lithosere, which refers to the ecological succession that occurs on bare rock.
- **Match:** Succession on bare rock → (iii) Lithosere

### Final Matches:
- Bacteria → (iv) Micro-consumers
- Green plants → (ii) Transducers
- Primary succession → (i) Prisere
- Succession on bare rock → (iii) Lithosere

### Summary of Matches:
1. Bacteria → Micro-consumers (iv)
2. Green plants → Transducers (ii)
3. Primary succession → Prisere (i)
4. Succession on bare rock → Lithosere (iii)

### Correct Option Code:
The correct option code based on the matches is:
- (iv), (ii), (i), (iii)
