What is the difference between absolute growth curve and absolute growth rate curve and their appearance?

Question

The 3rd type is the relative growth rate curve.
Why are they different from each other for a particular animal.

Answer 1

You could see the link below for different types of growth curves for animal development

However, there you can find different shapes for what I guess you refer to absolute growth curve.

The difference between absolute growth curve and absolute growth rate curve is that the second curve is actually the fist derivative of the first curve. Thus its shape will depend on the shape of your absolute growth curve.

I don't know for the relative curve (relative to what?)

Answer 2

Absolute Growth Rate

Answer 3

The growth rate curve is the 1st derivative of the growth curve. The relative growth rate is the ratio of those 2 curves. Another curve (of the 2d derivative) could be drawn to show the rate of change in the growth rate.
