QUIZ : Ecosystems more

ttp://www.enchantedlearning.com/biomes/pond/pondlife.shtml

in PowerPoint make a nine slide show of a Food Pyramid for a pond ecosystem

slide one: Title slide : use your names

Save the ppt in My Documents / your folder
name it:as: lastname lastname Pond

slide two: draw a better version of this pyramid, and show/label somehow that each level gets energy from the one before it.

slides 3-7 will each be one level of the pyramid, starting at the bottom,

what do you think is the important information to put on them?

What will you title each slide?

Should you have any pictures at each level? (yes)

hint: Be sure each trophic level slide includes:

	how energy is flowing (where their energy comes from, where it goes next);
	type energy used;
	trophic levels;
	at least three examples of organisms from each trophic level (from my list/linked)
