 People make windmills for electricity
 People cut down trees
Choose one biotic or abiotic factor in
your ecosystem & describe how a
change in one of these could your
ecosystem.
Change – take out deciduous tree:

If there were no deciduous trees, people would have no lumber

The squirrels would have no acorns for food

Birds would have no food or homes

No oxygen for people and animals

People would have no wood

If there were no leaves, soil would not be rich for farming

Less paper supplies
Other interesting facts:
