Transcript Ecosystems

Habitat
An environment that provides the things an
organism needs to live, grow and reproduce
Biotic Factors
The living parts of a habitat
clown fish
sea anemone
panda
bamboo plants
Abiotic Factors
The non-living parts of a habitat


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
population? Why or Why not?
Putting it all together

What is the difference between a community
and an ecosystem?

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