Week Four

Checked the ecosystem today and the aquatic area was orange and had a foul smell. We changed the water out because the decomposition area was seeping into it. This is evidence that material is circulating through the ecosystem. We put a straw into the top and middle of the ecosystem to allow the flys to travel back and forth, but it was taped shut when we checked it again this week. We would like to add more water lilies to the bottom or even other aquatic plants.
