=WELCOME TO OUR POND ECOSYSTEM PAGE!!!=

__Introduction__
Hi! We are four sixth grade students from the [|Amigos School] in [|Cambridge, Massachusetts]. As a part of our science class, we've been "Ecosystem Investigators", traveling from ecosystem to ecosystem in the [|Boston area.] The ecosystem the four of us have been studying is the pond ecosystem in Black's Nook Pond at the Maynard Ecology Center in Cambridge.



__Abiotic Things__
The abiotic (non-living things) in this ecosystem are: Air (oxygen and carbon dioxide) at 62 degrees Farenheit in October 2006, fresh water at 68 degrees Farenheit and with the pH of about 6 or 7 also in October, earth (rocks, sand, and dirt), and… The sun!

__Biotic Things__
The biotic or living things we found were **[|producers]**: [|algae], [|duckweed],plant-like plankton/[|phytoplankton], [|elodea] and [|bacteria]; **[|herbivores]****:** [|phantom midge larva], [|damselfly] nymph, [|threadworm], [|copepod], [|flatworm], animal-like plankton and turtles; **[|carnivores]:** [|mosquitoes], [|leeches], threadworms, turtles, frogs, heron, fish, flatworm; and **decomposers**: thread worms, flatworms,and bacteria. Those are some of the biotic things! It means that they were all alive.

Above and to the right is a picture of a part of Black's Nook pond and a small overhang of earth, which is where many of us (students) used plankton nets and sieves to find specimens to observe under the microscope.

This is a list you can refer to to see the things in the pond ecosystem. We show the **biotic** organisms: producers, herbivores, carnivores (there were no omnivores); and the **a****biotic** things.

This is an energy pyramid showing the sun, decomposers, producers, primary consumers (herbivores), secondary consumers (carnivores), and the tertiary consumers (also consumers) in Black's Nook Pond. .

These are two webs, an energy web of consumption above, and the things in the pond ecosystem below. In the web above, when an arrow points to another organism, the organism the arrow points to gets the energy from the organism that was pointing to it.
