the bottom of the ocean to the lower atmosphere. It consists of three layers:
which comprises of the water on the earth as well as water vapor in the air; and
the atmosphere, which is made up of the air that surrounds the earth. The living
effect on living organisms, these are considered abiotic factors. Examples of
biosphere, organisms live in special groupings. For instance, a population
is a population located in a certain area living among different species. An
ecosystem is yet a larger conglomeration of a population, a community, and
abiotic factors. Ecosystems can be aquatic or terrestrial. The earth’s aquatic
ecosystem is mainly made up of forests and deserts, which make up for 25% of the
earth’s surface. The role or function of an organism in a community is that
organism’s niche. An organism’s niche is an area picked by that organism based
predators. This niche provides the organism a place to live in. A habitat
remains consistent with an organism’s niche as well as provides the organism
with a place to reproduce. In this case, organisms may have the same habitat,
interactions between organisms. They are mutualism, commensalism, and
interaction with each other. An example is the honey bee and a flowering plant.
Commensalism only benefits one organism, but the other organism is not affected.
Parasitism only benefits one organism and harms the other organism, which most
dioxide in the atmosphere. This contributes to the greenhouse effect, which has
up about 78% of the earth’s air mixture. Oxygen makes up about 22% of the
earth’s air mixture, and pollutants make up about 1% of the earth’s air mixture.
Nitrogen is important in the development of organisms on earth, as the make
they make up DNA and other compounds crucial to the formation and sustenance of
life. Changes in an ecosystem are brought about by different factors. For
example, ecological succession brings about the replacement of one community by
another in an ecosystem. In other instances, organisms that colonize an area
with no community present are considered pioneer organisms. A climax community
is the final stage of development of organisms and can be disrupted by a major
catastrophe like a volcanic eruption.
