Population of 300,000 km so the population density is

structure is what the population is composed of, or it shows what is the make
up of a population. It divides the different gender of a place or community
specifically males and females of different age groups. The population pyramid
shows how the males and females of different age group is divided, it is the
graphical illustration of the division of the two. Below is an example of a
population pyramid. The
figure above shows how the two gender with different age groups are divided
considerably. The widest bar at the left side means that the largest population
in Kentucky are males with the age of 20-24 years old. While on the female
side, the largest population among the age groups are 0-4 years old. The reason
of the large number of males in Kentucky is because it is the location of a
large military installation. So the bars on the side determine the gender and
estimate the number of them while the middle part determine the age of the
different groups.

Density is the number of individuals per unit area. Population density is  determined by dividing the population by the
area. For example, if the Philippines has a population of 103 million people
and an area of 300,000 km so the population density is  323.33 persons per square kilometer. There
are two reasons that can affect population density, the input and the output.
The inputs can be high birth rate or immigration. High immigration or birth
rate can affect the density if it is not balanced with the output which is
death or emigration. If there is high inputs and low output, it can cause

Energetic, Biomass and Production

flow is the transfer of energy from trophic level to another trophic level.
Solar energy is transferred from the sun to the plants or the producers and
will be taken in by the primary consumer whereas the energy transfers, it only
transfer 90% of energy will be lost due to respiration. So the first consumer
only get 10% of energy while 1% for the secondary consumer and only 0.1% left
for the tertiary consumer. A lot of energy is lost between trophic levels, as a
result the last consumer receives the lowest energy.



are two general life strategists; these are the r and k strategists.

living beings portrayed as r-strategists regularly live in unsteady, eccentric
conditions. Here the capacity to recreate quickly (exponentially) is
imperative. Such life forms have high fertility (glossary) and generally little
interest in any one descendants singular, they are normally powerless and
subject to predation and the changes of their condition. The “vital
plan” is to surge the living space with descendants so that, paying little
heed to predation or mortality, at any rate a portion of the offspring will
make due to recreate. Living beings that are r-chosen have short life
expectancies, are by and large little, snappy to develop and squander a
considerable measure of vitality. Examples of these are salmon, corals, insects
and bacteria.

then again involve more steady situations. They are bigger in estimate and have
longer futures. They are more grounded or are better secured and by and large
are more vitality productive. They deliver, amid their life expectancies, less
descendants, yet put a more prominent interest in each. Their regenerative
procedure is to develop gradually, live near the conveying limit of their
living space and deliver a couple of offspring each with a high likelihood of
survival. Normal K-chose living beings are elephants, and people. The table
beneath compresses a portion of the contrasts between r-life forms and K-life
forms. Examples of these are monkeys, humans, and elephants.
