Biological decay and release from ocean are important natural processes for the formation of

Options

A. `O_(2)`
B. `CO_(2)`
C. `CO`
D. `SO_(2)`

Answer

To solve the question regarding the importance of biological decay and release from the ocean in natural processes, we can break it down step by step:

### Step 1: Understand the Marine Cycle
The marine cycle, also known as the biological pump, involves the processes that occur in the ocean related to marine organisms. This includes both living organisms and the organic matter they produce.

**Hint:** Think about how marine life contributes to the cycling of nutrients and gases in the ocean.

### Step 2: Identify the Role of Marine Organisms
Marine organisms, such as plants and animals, are primarily composed of organic matter, which contains carbon. When these organisms die, they do not just disappear; they undergo a process of decay.

**Hint:** Consider what happens to organic matter when it is no longer part of a living organism.

### Step 3: Decomposition Process
When marine organisms die, they sink to the bottom of the ocean. At the ocean floor, they decompose due to the action of bacteria and other decomposers. This decomposition process releases various gases.

**Hint:** Focus on the products of decomposition and what gases might be released during this process.

### Step 4: Formation of Carbon Dioxide
During the decomposition of organic matter, carbon dioxide (CO2) is produced. This gas is released into the surrounding water and is found in higher concentrations in the deeper parts of the ocean.

**Hint:** Think about the relationship between organic matter decay and the gases produced.

### Step 5: Conclusion
Based on the understanding of the marine cycle and the decomposition of marine organisms, we can conclude that biological decay and release from the ocean are important natural processes for the formation of carbon dioxide.

**Final Answer:** The correct answer is **carbon dioxide (Option B)**.
