CHANGES IN AN ECOSYSTEMCAUSED 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 DAMSBeavers live in rivers or streams. They build dams which stop the flow of the water.
THINK & DISCUSSHow 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 GROUNDEarthworms spend most of the time underground, digging tunnels, or burrows.
THINK & DISCUSSHow 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 speciesDID YOU KNOW?
All of these animals were brought to North American from other continents
CAN YOU GUESS THE CONTINENT FOR EACH ANIMAL?
DISCUSS AT YOUR TABLE.
CAT SHEEP
GUINEA PIG
HORSE
Introducing a new species
CAT AFRICA
EUROPE
SHEEPASIA
GUINEA PIG
SOUTH AMERICA
HORSEEUROPE
THINK & DISCUSSHow 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 & DISCUSSHow 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 & DISCUSSHow 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 & DISCUSSHow does building a UDF store effect the ecosystem?
How are these changes BENEFICIAL? DETRIMENTAL? NEUTRAL?
After discussion, we will complete our note sheet together.
