Why Our Eco-Column Will Be Self-Sustaining


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.
