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.
Niche
•How a certain species meets its needs for food
and shelter, how and where it survives, and
where it reproduces
Habitat
Where an organism lives out its life
Where you live
Describe your own community
and the population you will find
there.
