Which of the following is the logical sequence of carbon cycle ?

Options

A. Photosynthesis-consumer-decomposer
B. Photosynthesis-decomposer-consumer
C. Consumer-photosynthesis-decomposer
D. Decomposer-photosynthesis-consumer

Answer

### Step-by-Step Solution for the Carbon Cycle

1. **Photosynthesis**: The carbon cycle begins with photosynthesis, where plants (autotrophs) absorb carbon dioxide (CO2) from the atmosphere and convert it into glucose (C6H12O6) using sunlight. This process captures carbon in a form that can be used by living organisms.

2. **Consumption**: The glucose produced by plants serves as food for herbivores (primary consumers) and subsequently for carnivores (secondary consumers). When these organisms consume plant material, they incorporate carbon into their bodies.

3. **Respiration**: Both plants and consumers undergo respiration, a process in which they convert glucose back into energy. During respiration, carbon dioxide is released back into the atmosphere as a byproduct.

4. **Decomposition**: When plants and animals die, decomposers (like bacteria and fungi) break down their bodies. This process releases carbon back into the soil and atmosphere, completing the cycle.

5. **Return to Atmosphere**: The carbon released during respiration and decomposition returns to the atmosphere as carbon dioxide, which can again be used by plants for photosynthesis, thus continuing the cycle.

### Logical Sequence of the Carbon Cycle
The logical sequence of the carbon cycle can be summarized as:
1. Photosynthesis
2. Consumption
3. Respiration
4. Decomposition
5. Return to Atmosphere
