Today, we decided against placing two mice into the bio-bubble and instead we placed to fire-bellied toads inside the bio-bubble. We also got to place our Salamander inside the bio-bubble today as well. We observed that now that we had some form of producer inside the ecosystem that none of our grasshoppers had died. For some reason though, everyone's Betta Fishes, in every habitat that had one, jumped out of the water and died. We have a little tunnel type thing made out of bark for the insects to climb and for the frogs and salamanders to hide under. We also spray the inside down with water everyday hoping to get our water levels just right inside the ecosystem.

Can you describe the food chain and the flow of energy that is occurring in your system. Why did you choose frogs over toads?

The food chain would start at the light source which is giving the producers energy. The producers then get eaten by the primary consumers, the primary by the secondary, and so on. Only 10% of the energy is passed on between each organism, the rest of the energy is lost elsewhere. We actually chose toads over frogs. There was no specific reason. And technically the use of the common names "frog" and "toad" have no taxonomic justification. The only difference between the two is that the toad has rougher and dryer skin and that they can live in dryer habitats.
