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 <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.

Answer:
the answer is the second option.
carbohydrates, lipids, proteins and nucleic acids are biological molecules essential to sustain life in living organisms.
Answer:
Energy from the sun light
Explanation:
This happens directly or indirectly.
Producers use this energy directly to make organic material, via photosynthesis, that gets passed down the food chain. Herbivores and other organisms will get this energy indirectly by eating the organic material made by the producers using this light energy.
So all the organisms someway get their energy from the sun light.
