2. Learner Expectations
Interactions Between Living Things and
Their Environment.
You will investigate how living things interact with
one another and with non-living elements of their
environment.
Learning Expectations:
Investigate the relationships among organisms in a
specific ecosystem.
3. In this lesson, you will:
Learn how living things interact
with one another and with non-
living elements of their
environment.
4. What is a Population?
A population is one species living
in a specific area.
For example, all foxes living in an
area form a population.
Another example, all dandelions
growing in an area form another
population.
5. What is a Community?
A community is formed from all living
populations found in an area.
All the foxes, dandelions,
grasshoppers, snakes, hawks, deer, and
skunks living in one area each form
their individual populations, but
together make up a community.
6. What is a Ecosystem?
An ecosystem is formed by the
interactions between all living and
non-living things
How do living and non-living
things interact in an environment?
7. What is Ecology?
Ecology is how living and non-living
things affect each other in their
environment.
We have already named several living
things found in a community. Can you
name non-living things in your
community?
9. How non-living and living things
affect each other
Building more homes drives many animals out of
their natural habitats or communities.
Littering can destroy an animals habitat.
Air pollution from automobiles and factories will
affect the quality of life for all living things in a
community, including people.
