<span>Age structure would help scientists determine if the problem exists with young or old dolphins.
The age structure shows the distribution of the ages of the individuals in a population. This not only shows the type of change taking place in the population (increasing, decreasing or staying the same) but also is able to help us relate problems to ages.
