Growth curve indicates
(a) Growth rate
(b) A growth parameter at various intervals
(c) Absolute growth
(d) Absolute increase

Options

A. Growth rate
B. A growth parameter at various intervals
C. Absolute growth
D. Absolute increase

Answer

To solve the question regarding what a growth curve indicates, let's analyze each option step by step:

1. **Understanding the Growth Curve**:
- A growth curve is a graphical representation that shows how a particular organism grows over time.
- It typically illustrates different phases of growth such as lag phase, log phase (exponential growth), and stationary phase.

2. **Analyzing the Options**:
- **(a) Growth rate**: This refers to the speed at which growth occurs, but a growth curve itself does not directly indicate the rate; it shows the growth pattern over time.
- **(b) A growth parameter at various intervals**: This option suggests that the growth curve represents growth measurements taken at different time intervals, which aligns with the nature of growth curves.
- **(c) Absolute growth**: This term implies a total growth measurement without considering the time factor, which is not what a growth curve represents.
- **(d) Absolute increase**: This refers to the total increase in size or number, which again does not capture the essence of a growth curve.

3. **Conclusion**:
- Based on the analysis, the most accurate representation of what a growth curve indicates is **(b) A growth parameter at various intervals**. This option reflects that the growth curve provides information about growth at different time points.

### Final Answer:
(b) A growth parameter at various intervals
