Habitat

organism needs to live, grow and reproduce

Biotic and Abiotic Factors
• Biotic = living
components of an
ecosystem including
anything that was once
alive.
• Abiotic = non living
components of an
ecosystem. These were
never alive.
Putting it all together

What basic needs are met by an organisms
habitat?

Food water shelter and other things it needs
to live.
Putting it all together

Why do different organisms live in different
habitats?

Because different organisms have different
needs for survival.
Putting it all together

Using the word photosynthesis, explain
why water and sunlight are two abiotic
factors that are important to all organisms
Species
A group of organisms
that are physically
similar and that can
mate and produce
fertile offspring.
Population
All the members
of one species in
a particular area.
Community
All the different populations
that live together in an area.
Ecosystem
A community of
organisms that live in an
area along with their non
living surroundings
Ecology
The study of how
living things
interact with each
other and their
environment.

Would all the
trees in a forest
make up a

Why or Why
not?

Why do ecologists
study both the biotic
and abiotic factors in
an ecosystem?
