Our Eco-Column will be self sustaining due to these reasons:
Abiotic (non-living):
> The water which has overflowed from the aqua zone will
be recycled by putting it back into the Terra Zone.
> The rich nutrients in the soil will help the plant grow and provide food for the earthworms.
Biotic (living):
> The earth worms in the Terra and Decomp Zone will recycle
the nutrients back into the soil.
> The plants in the Terra Zone will create their own
oxygen by photosynthesizing.
> The Sun will be the only light source. No artificial
light will be used.
> Insects will feed off other insects.
