Our Original Drawing Idea Of The Eco-Column

-

We have kept to our original plan except for the fact that we are using earth worms instead of snails and that we are using radishes in the Terra-Zone instead of a bean plant.

Terra Zone (By A.Gordon) – In this sector of the Eco-Column, we have a radish, earth worms and a rock. A filtration system allows water to filter through into the sector below know as the Decomp zone.

Decomp Zone (By D.Rowell) - In the Decomp Zone we have apples and bark which will hopefully decompose and attract fruit flies. We will also have earthworms which will help recycle the nutrients back into the soil. Water flows into it from the filtration system in the Terra zone. The Decomp Zone uses the same filtration system into the aqua zone.

Aqua Zone (By D.Dell) - In the Aqua zone there is a filtration system leading down from the Decomp zone above. There is water in this zone from a pond and some small stones; a practical habitat for any water insects.
