Ecology
, the study of relationships between organisms and the environment, has been
a focus for human study for as long as we have existed as a species.
Ecologist
may study
individual organisms in an entire forest or grassland, or even the whole earth.
The ecology of
the entire forest, grassland, or lakes for examples are treated as
ecosystems.
Broadly, the
ecosystem consists of two basic interacting components-the living or
biotic
, and the
nonliving (physical and chemical, or
abiotic
(Smith and Smith, 2012).
The ecosystems of
earth form the planetary ecosystem or
biosphere.
Organism
which refers to individual organism in relation to other organisms.
Populations
refer to the group of organisms of the same species and how they interact with
each other.
Communities
which refers to natural assemblages of populations of different species and
their interactions.
Ecosystems
