A community refers to the total number of populations that inhabit a
specific location or area. This is part of the levels of organization of life. Arranged from the least complex to most
complex it falls 8th in the category. Below are the organization of life:<span>
a. Organelles - the basic part of a living
organism. It refers to the different structures of the cell, whether
prokaryotic or eukaryotic. (Ex. Mitochondria, nucleus)
b. Cells - building blocks of life that are
composed of different molecules responsible for the function of an organism.
(Example: prokaryotic, eukaryotic cells)
c. Tissues - combinations of cells that carry
out a specific function in an organism. (Example: Human skin)
d. Organs - collections of tissues that perform
specific functions. (Ex. heart, lungs)
e. Organ Systems - composed of interconnected
organs that function as a whole. Many organisms, particularly mamamals, are
composed of organ systems. (Ex. respiratory, circulatory systems)
f. Organisms – individual entities that
specifically make-up a population. (Ex. Each tree in the forest is an organism,
each animal in sea is an organism)</span>
g. Population – species living within a specific location. It could be
the same or different species that inhabit a place. (Ex. Birds are species in
the forest as well as bears)
h. Community – refers to the total number of populations that inhabit a
specific location. (Ex. All of the trees, insects, birds that inhabit the
forest are a community)
i. Ecosystem – consists of all living things that function together as a
group which also includes the non-living parts of the environment. (Ex. Rain
water, nitrogen in the soil)
<span>j. Biosphere – the highest organization of life that consist of all the
collection of ecosystems in the planet. It includes the land, air, water, even
