Ecotower Observation #3 4/8/2011

1. Animals:
        -Worms: We burried three worms in the soil in our ecotower so we don't know if they are alive or not.
        -Snails: The snails we had died.
        -Crickets: All of our crickets are dead.
        -Beta Fish: The fish we had is still living.

2.We think that the algae is keeping the fish alive. The animals died at the top died from not enough of oxygen. The worms are still unknown because we can't see them The snails died in the water.

3. Plants:
       -Beans Plant: It grew but is starting to die.
       -Algae: It's turning a brown color.
       -Other Plants: They are beginning to die.

4. The plants are starting to die because they aren't getting anough carbon dioxide. The algae is turning brown from lack of oxygen

5. The water is getting yellower. It has particles floating around it. The algae is sinking.

6.

7. I dont't think the fish will die until the algae dies completely
