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.
Maple trees show us the percentage of tress through the different ages and this is due to the population density, distribution, and age structure.
What is a maple tree?
A maple tree is a shrub and consists of 132 specie most of them native to Asia and also appear in Europe, North America, and Africa.
The tree grows closely hence showing the density and distribution of the tree population.
The age structure of the tree is for 300 - 400 years and often occurs in spring and summer. Thus the 56 trees that density living on 20 acres of land is distributed.
