Measurement and the comparison of total growth per unit time is known as

Options

A. Absolute growth rate
B. Relative growth rate
C. Both ( a) and (b)
D. None of these

Answer

To solve the question regarding the measurement and comparison of total growth per unit time, we can follow these steps:

### Step 1: Understand the Terms
- **Absolute Growth Rate**: This refers to the total growth of an organism or system measured over a specific period of time. It is a straightforward measurement of growth without any comparison to other factors.

- **Relative Growth Rate**: This measures the growth of an organism or system in relation to its size or mass at a given time. It often provides a percentage or ratio that reflects how growth changes over time relative to the initial size.

### Step 2: Analyze the Question
The question specifically asks for the measurement and comparison of total growth per unit time. This indicates that we are looking for a term that encompasses both measurement and comparison.

### Step 3: Compare the Options
- **Absolute Growth Rate**: This option fits the description as it involves measuring the total growth over time.

- **Relative Growth Rate**: This option focuses on growth relative to size but does not emphasize total growth measurement.

- **Both A and B**: This option suggests that both terms apply, but since the question is specific about total growth, this option is not correct.

- **None of These**: This option can be dismissed as we have identified a suitable term.

### Step 4: Conclusion
Based on the definitions and analysis, the correct answer is **Absolute Growth Rate**.

### Final Answer
The measurement and comparison of total growth per unit time is known as **Absolute Growth Rate**.
