Question

Frank counts 56 maple trees living on a 20-acre tract of land, and the data allows him to calculate the of the maple trees on the land. He observes that most of the maple trees grow closely together in groups of 6 to 8 trees, which describes the . The of the maple trees shows the percentages of trees of different ages.

Answer 1

Answer:

population density

population distribution

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 population density 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 population distribution.

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 age structure 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.
