Which life process ensures that a plant or animal species will not disappear from the earth ?

Options

A. Reproduction
B. Metamorphosis
C. Cloning
D. None of the above

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which life process is crucial for ensuring that a plant or animal species does not become extinct.

2. **Identifying the Options**: The options provided are:
- A) Reproduction
- B) Metamorphosis
- C) Cloning
- D) None of the above

3. **Analyzing the Options**:
- **Metamorphosis**: This is a developmental process that some animals undergo (like frogs and butterflies) but does not directly relate to the survival of a species.
- **Cloning**: This is a method of reproduction that can produce identical organisms but is not a natural process for most species.
- **None of the above**: This option implies that none of the listed processes are responsible for species survival.

4. **Focusing on Reproduction**: Reproduction is the biological process through which new individual organisms are produced. It is essential for the continuation of a species as it allows for the generation of new individuals, ensuring that the species can survive over generations.

5. **Conclusion**: Since reproduction is the process that allows for the continuation of species, it is the correct answer to the question.

6. **Final Answer**: The life process that ensures that a plant or animal species will not disappear from the earth is **Reproduction** (Option A).
