An ecosystem consists of all the living and non-living things in an area and their interactions. It includes biotic factors like plants, animals and other organisms, as well as abiotic factors such as soil, water and weather. Individuals make up populations of the same species, and all the populations that live in a given area together form the biological community. Ecosystems can range in size from small areas under rocks to large regions like forests.

1. What are
the parts
of an
ecosystem?

2. Environment
All the living and non-living
things that surround you (an
organism/individual).
Example:
- Living and non-living things around you
at home.
- Living and non-living things around you
in the classroom.

3. All environments are made up of two
parts.
Living things Non-living
(People, plants and things
(Water, air, soil
animals) and weather)

4. Parts of an environment affect
one another in many ways.
Example:
- Type of Soil affects what plants can
grow in it.
- Clean water helps animals and plants
stay healthy.
- Animals eat plants.

5. Ecosystem
All the living and non-living
things in an area.

6. Ecosystems can be:
Very small Very big
Ex. Space Ex. Forest
under a rock
(home to
insects and
tiny plants)

7. The ecosystem under the rock
and in the forest has a:
Climate
(Average weather in an area
over many years)

8. One plant or animal is an
Individual

9. Examples of individuals
One blueberry One honey bee
bush
One blue jay

10. Population
A group made up of the same
kind of individuals living in the
same ecosystem.

11. Examples of population
A population of green
tree frogs.

12. A wolf pack (3-20 wolves).
A population of wolves may have many wolf packs.

13. Some populations can live in more than
one kind of ecosystem.
Example:
Red-winged blackbird (lives in wetlands and
other areas)

14. Some populations can live in only one
kind of ecosystem.
Example:
Hine’s emerald dragonfly

15. Community
All the populations that live in
the same place.

16. Everglades national park has many
populations
Example: Alligators, bobcats, raccoons
and mosquitoes.
