D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Decomposition of organic matter
 **Related Topics**: Aerobic and anaerobic respiration, microbial activity, greenhouse gases
 **Prerequisites**: Basic understanding of cellular respiration and the chemical composition of organic matter.
## SOLUTION PATHWAY
**Given Information**:
  Decomposition of organic matter in composting.
  Options: $O_2$, $N_2$, $CO_2$, $H_2$
**Method & Steps**:
 1. Identify the primary process involved in composting: Decomposition of organic matter is primarily driven by microbial activity. Microbes break down complex organic molecules into simpler compounds.
  Reasoning: This process involves various metabolic pathways.
  Formula/Rule:  Not directly applicable, but understanding the chemical reactions involved is crucial.
 2. Determine the primary gaseous byproduct: The main product of microbial respiration (both aerobic and anaerobic) in composting is carbon dioxide ($CO_2$).  While other gases are produced, $CO_2$ is released in significantly larger quantities.
  Working: Aerobic respiration: $C_6H_{12}O_6 + 6O_2 ightarrow 6CO_2 + 6H_2O$. Anaerobic respiration produces $CO_2$ as well, along with other products like methane.
  Key Point: The type of respiration (aerobic or anaerobic) influences the exact composition of gases produced, but $CO_2$ remains a dominant product.
 3. Select the correct option: Carbon dioxide ($CO_2$) is the primarily released gas during composting.
  Result: C
  Verification: Composting processes generate significant amounts of $CO_2$, which can be measured experimentally.
 ## OPTION ANALYSIS
A :x: Oxygen ($O_2$) is consumed during aerobic decomposition, not primarily released.
B :x: Nitrogen ($N_2$) is primarily present in the air and is not a major product of decomposition. Some nitrogen compounds might be released, but not as the primary gas.
C ✓: Carbon dioxide ($CO_2$) is the main gaseous product of the decomposition of organic matter, regardless of whether it is aerobic or anaerobic decomposition.
D :x: Hydrogen ($H_2$) is produced in smaller quantities during anaerobic decomposition; $CO_2$ is produced in much larger amounts.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the reactants and products of decomposition:  Remembering that oxygen is consumed during aerobic decomposition, not released as a product.
  2.Overlooking the dominance of $CO_2$: Recognizing that while other gases are present, $CO_2$ is the major component of the gas released during composting.
 **Quick Tips**:
  1.Focus on the dominant metabolic pathway involved in composting: Microbial respiration.
  2.Remember that $CO_2$ is a major product of both aerobic and anaerobic respiration.
