Answer:
The answers are the age of the organism and the environmental conditions during the organism’s life.
Step-by-step explanation:
The growth varies during the life of an organism, and it can be observed in the growth rates during the entire life. Growth rate is represented in a graph as the slope of the curve.
Growth rate varies between different developmental stages through life. For example, the growth rate in humans is faster in children and young people than in adults. By observing the growth rate patterns, you can determine an approximation of the age of an organism.
In the other hand, growth is dependent from environmental conditions that the organism has been exposed. For example, in frogs, growth rate increase when temperature increases. Another environmental factor that can affect growth is feeding quantity and quality. So, if you know the general growth pattern of an organism you can compare it to identify differences in the growth rate that indicates an effect of environmental conditions.
