Ecosystems
An ecosystem is all living and
nonliving things in an area.
Ecosystem is derived from the
Greek word oikos, for “house,”
eco-is the combining form
meaning “environment or
habitat.”
An Ecosystem may be very small
such as:
A backyard
A pond
A playground
Some may be very large like:
The deserts of Africa
The rain forest of Brazil
The saltwater oceans
All ecosystems have the same
parts:
Abiotic Factors
Biotic Factors
Abiotic Factors
The nonliving parts of an ecosystem.
They include water, minerals, sunlight, air,
climate, and soil.
Biotic Factors
The living parts of an ecosystem.
They include animals, plants, fungi, protists,
and bacteria.
All organisms of a species living
in the same area make up its
population.
All the populations living in an
area make up a community.

Where you live
Describe your own community
and the population you will find
there.
