Given below is a comparision of elements present in non-living and living matter. Which of these is incorrect:

Options

A. `{:(,"Element", "% weight of Earth's crust","% weight of Human body"),(,"(1) Silicon"," 27.7","Negligible"):}`
B. `{:(,"Element", "% weight of Earth's crust","% weight of Human body"),(,"(2) Carbon"," 0.03"," 18.5"):}`
C. `{:(,"Element", "% weight of Earth's crust","% weight of Human body"),(,"(3) Calcium"," 10"," 15"):}`
D. `{:(,"Element", "% weight of Earth's crust","% weight of Human body"),(,"(4) Nitrogen"," Very little"," 3.3"):}`

Explanation

To determine which statement is incorrect regarding the comparison of elements present in non-living and living matter, we will analyze the percentages of various elements in the Earth's crust and the human body.

### Step-by-Step Solution:

1. **Identify the Elements and Their Percentages**:
- We will compare the percentages of silicon, carbon, calcium, and nitrogen in the Earth's crust and the human body.

2. **Silicon**:
- **Earth's Crust**: Approximately 27.7% (second most abundant element).
- **Human Body**: Approximately 1 to 2 grams (negligible percentage).
- **Conclusion**: The statement regarding silicon is correct.

3. **Carbon**:
- **Earth's Crust**: Approximately 0.032%.
- **Human Body**: About 18 to 19%.
- **Conclusion**: The statement regarding carbon is correct.

4. **Calcium**:
- **Earth's Crust**: Approximately 3% (fifth most abundant element).
- **Human Body**: Approximately 1 to 2% (not 10% as stated).
- **Conclusion**: The statement regarding calcium is incorrect.

5. **Nitrogen**:
- **Earth's Crust**: Very little (found in some rare minerals).
- **Human Body**: Approximately 3% (important for amino acids and DNA).
- **Conclusion**: The statement regarding nitrogen is correct.

6. **Final Conclusion**:
- The incorrect statement is regarding calcium, where it was stated that the percentage in the human body is 10%, while it is actually about 1 to 2%.

### Summary of Findings:
- **Silicon**: Correct.
- **Carbon**: Correct.
- **Calcium**: Incorrect (stated as 10%, actual is 1-2%).
- **Nitrogen**: Correct.
