Populations of two or more different species
occupying the same geographical area.
Community
A group of individuals of a single species that
live in a particular area and interact with
one another..
This causes a population to decrease in size, and
affects the growth or reproduction of certain
species.
This is the observed process of change in the
species structure of an ecological community
over time; it begins with relatively few
pioneering plants and animals and develops
through increasing complexity.
An ecological community, which has all the
plant and animal community existing in a
stable state.
This is the degree of variation of life which
refers to genetic variation, species variation,
or ecosystem variation within an area, biome,
or planet.
This ecological process refers to the regrowth of
a habitat in the area where a disruptive event has
occurred and eliminated the existing, above ground
plant life of the natural habitat; some plants and
animals still exist.
The ecological process when all life is wiped out
due to a massive events such as a forest fire, where
previous life forms are destroyed and later replaced
by a new species that is adaptable to conditions.
A major geographical area of ecologically similar
communities of plants, animals, and soil organisms,
with particular patterns of ecological succession
and climax vegetation.
This is a natural unit consisting of all plants,
animals and micro-organisms in an area functioning
together with all the non-living physical factors of the
environment.
