CHANGES IN AN ECOSYSTEMCAUSED BY ANIMALS - INCLUDING HUMANS
![Page 40: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/40.jpg)
This presentation will ask you to THINK – DISCUSS – WRITE
But first, here is some background information……
![Page 41: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/41.jpg)
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
![Page 42: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/42.jpg)
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
![Page 43: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/43.jpg)
DETRIMENTAL CHANGES These changes mean BAD THINGS for
some part of the ecosystem
Some changes are DETRIMENTAL for some parts of the ecosystem
![Page 44: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/44.jpg)
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
![Page 45: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/45.jpg)
Let’s look at some examples…
Can you name this animal?
![Page 46: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/46.jpg)
This animal is a BEAVER
DISCUSS AT YOUR TABLE – What are some things you know about the beaver?
![Page 47: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/47.jpg)
BEAVERS BUILD DAMSBeavers live in rivers or streams. They build dams which stop the flow of the water.
![Page 48: Life Science Unit](https://reader035.vdocuments.us/reader035/viewer/2022062301/56815f01550346895dcdbe9b/html5/thumbnails/48.jpg)
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.

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.

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.
