age structure

Explanation:

if we look at this question; it looks glaring that it correlates with a fill in the blank type of question.

So, from the question:

Frank counts 56 maple trees living on a 20-acre tract of land, and the data allows him to calculate the <u>population density</u> of the maple trees on the land.

In an ecological succession, population  density refer to species of  a common genera in specific geographical setting. It helps to measure the exact number of organism inhabitant a unit area of a place.

He observes that most of the maple trees grow closely together in groups of 6 to 8 trees, which describes the <u>population distribution. </u>

Population distribution is the spread of organism over a region in a geographic ecological setting. The pattern of distribution of organism may be uniform , in some  organism they are largely dispersed and in some they are clumped together.

The<u> age structure </u>of the maple trees shows the percentages of trees of different ages.

The age structure is also a term used in ecology which is normally use to predict the proportion of growth of organisms. Age structure  of  species in the environment speaks volume about their  distribution of age.
