A biome is a community of animals and plants spreading over an extensive area,
sometimes thousands of miles in length or width, with relatively uniform climatic conditions

CHANGES IN AN
ECOSYSTEM
CAUSED BY ANIMALS INCLUDING HUMANS
This presentation will ask
you to THINK – DISCUSS –
WRITE
But first, here is
some background
information……
EVERYTHING CHANGES…
 Things done by animals cause changes
within an ecosystem
 These changes can be BENEFICIAL,
DETRIMENTAL, or NEUTRAL to other
parts of the ecosystem
Discuss at your table what you think these
three words might mean
BENEFICIAL CHANGES
 These changes mean GOOD THINGS
for some part of the ecosystem
 A change in an ecosystem is
BENEFICIAL for some parts of the
ecosystem
DETRIMENTAL CHANGES
 These changes mean BAD THINGS for
some part of the ecosystem
 Some changes are DETRIMENTAL for
some parts of the ecosystem
NEUTRAL CHANGES
 These changes mean NEITHER good
things nor bad things for some part of the
ecosystem
 Some changes are NEUTRAL for some
parts of the ecosystem – these changes
have NO EFFCT on certain parts of an
ecosystem
Let’s look at some
examples…
Can you
name this
animal?
This animal is a BEAVER
DISCUSS AT YOUR
TABLE – What are
some things you
know about the
beaver?
BEAVERS BUILD DAMS
Beavers live in
rivers or
streams. They
build dams
which stop the
flow of the
water.
THINK & DISCUSS
How did the beaver building a
dam change the ecosystem?
How are these changes
BENEFICIAL?
DETRIMENTAL? NEUTRAL?
After discussion, we will
complete our note sheet
together.
Here’s another example….
Can you
name this
animal?
This animal is an
EARTHWORM
DISCUSS AT YOUR
TABLE – What are
some things you
know about the
earthworm?
EARTHWORMS BURROW
IN THE GROUND
Earthworms
spend most of
the time
underground,
digging
tunnels, or
burrows.
THINK & DISCUSS
How does an earthworm
burrowing change the
ecosystem?
How are these changes
BENEFICIAL?
DETRIMENTAL? NEUTRAL?
After discussion, we will
complete our note sheet
together.
HOW CAN HUMAN
CHANGES EFFECT AN
ECOSYSTEM?
Introducing a new species
DID YOU KNOW?
All of these
animals were
brought to North
American from
other continents
CAT
SHEEP
CAN YOU GUESS
THE CONTINENT
FOR EACH
ANIMAL?
DISCUSS AT
YOUR TABLE.
GUINEA
PIG
HORSE
Introducing a new species
CAT
SHEEP
AFRICA
ASIA
EUROPE
GUINEA
PIG
SOUTH
AMERICA
HORSE
EUROPE
THINK & DISCUSS
How does introducing a new
species of animal change the
ecosystem?
How are these changes
BENEFICIAL?
DETRIMENTAL? NEUTRAL?
After discussion, we will
complete our note sheet
together.
HUMANS HAVE ALSO
INTRODUCED NEW SPECIES OF
PLANTS
Asian Blight Fungus
THINK & DISCUSS
How does introducing a new
species of plant effect the
ecosystem?
How are these changes
BENEFICIAL?
DETRIMENTAL? NEUTRAL?
After discussion, we will
complete our note sheet
together.
THERE WAS ONE HUGE
DETRIMENTAL EFFECT…..
The Asian Blight
Fungus fed on the
American
Chestnut Tree –
wiped out 180
million acres of
this tree and the
result was 10
species of moths
went extinct.
Another human
effect…CONSTRUCTION
The BUTLER
COUNTY
REGIONAL
HIGHWAY was
completed December
13, 1999
THINK & DISCUSS
How does building a new
highway effect the ecosystem?
How are these changes
BENEFICIAL?
DETRIMENTAL? NEUTRAL?
After discussion, we will
complete our note sheet
together.
MORE CONSTRUCTION…
In 2006, a new
UDF store was
opened at the
corner of 747
and Princeton
Road.
THINK & DISCUSS
How does building a UDF
store effect the ecosystem?
How are these changes
BENEFICIAL?
DETRIMENTAL? NEUTRAL?
After discussion, we will
complete our note sheet
together.
