________ is a life process that is not essential for an individual's survival but for survival of the species.

Options

A. Growth
B. Reproduction
C. Respiration
D. Nutrition

Explanation

**Step-by-Step Solution:**

1. **Identify the Life Processes**: The question asks for a life process that is not essential for an individual's survival but is crucial for the survival of the species. The main life processes to consider are growth, reproduction, respiration, and nutrition.

2. **Analyze Growth**: Growth is a fundamental process for an individual. Without growth, an organism cannot develop or sustain life. Therefore, growth is essential for individual survival.

3. **Evaluate Reproduction**: Reproduction is the process by which organisms produce offspring. An individual can live without reproducing; for example, some people may choose not to have children or may be unable to reproduce. However, if no individuals reproduce, the species will eventually become extinct. Thus, reproduction is not essential for individual survival but is critical for species survival.

4. **Consider Respiration**: Respiration is vital for an individual's survival. It involves the exchange of gases and is necessary for energy production in cells. Without respiration, an individual cannot survive, making it an essential life process.

5. **Examine Nutrition**: Nutrition refers to the intake of food and nutrients necessary for maintaining health and energy. Like respiration, nutrition is essential for individual survival. Without proper nutrition, an individual can suffer from malnutrition and ultimately die.

6. **Conclusion**: After analyzing all the options, the only life process that is not essential for an individual's survival but is crucial for the survival of the species is **reproduction**.

**Final Answer**: Reproduction
