B. Chemical Energy `rarr` Light Energy `rarr` Heat
C. Heat `rarr` Light Energy `rarr` Chemical energy
D. Light Energy `rarr` Chemical energy `rarr` Heat.

Answer

To determine the correct sequence of energy transformations in photosynthetic organs, we can break down the process of photosynthesis step by step.

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy. This process primarily occurs in the chloroplasts of plant cells.

2. **Role of Light Energy**: The process begins when light energy from the sun is absorbed by chlorophyll, the green pigment found in plants. This absorption of light is crucial for initiating photosynthesis.

3. **Excitation of Electrons**: When chlorophyll absorbs light energy, it becomes excited, leading to the loss of electrons from the photosynthetic reaction center. This is a critical step in the conversion of energy.

4. **Conversion to Chemical Energy**: The energy from the excited electrons is then used to convert light energy into chemical energy. This chemical energy is stored in the form of glucose and other organic compounds produced during photosynthesis.

5. **Release of Heat Energy**: After the conversion of light energy into chemical energy, some of this energy is eventually released as heat. This is a natural byproduct of the energy transformations that occur during photosynthesis.

6. **Final Sequence**: Therefore, the correct sequence of energy transformations in photosynthetic organs is:
- Light Energy → Chemical Energy → Heat

### Conclusion:
The correct answer to the question "Which is correct for photosynthetic organs?" is:
- Light Energy, Chemical Energy, Heat.
