How it will be self sustaining
An aquatic zone
supplies water, a terrestrial zone (through plants) supplies oxygen and removes
carbon dioxide, the decomposition zone gives off nutrients by decomposing
leaves, twigs and fruit. The aquatic zone is at the bottom because it could not
be put on a higher level due to gravity and the water will evaporate up the eco
column for the plant to survive. The terrestrial zone is on top of the water
and on top of the decomposition zone. We have holes for fruit flies to enter
the decomposition zone which will support the system. Earthworms have been
placed in the Terrestrial and Decomposition zone because Earthworms move
through the ground, recycling dead and decomposing organic material back into
the soil, re distributing nutrients and improving water drainage .Fruit has
been placed in the decomposition so that it can supply nutrients to the
ecosystem. Algae has been placed in the aqua zone to create oxygen by breathing
in Co2 and giving off oxygen. Therefore, in order for the column to survive, it
truly has to be self sustaining. An ecosystem is a unit of nature in which
living and non living things are found and have dynamic relationships where
they interact with one another. This is why in our eco column we have abiotic
and biotic features so it can be self sustaining as a ecosystem. These points
suggest that are eco column will be self sustaining as each part in each zone
help one another and each zone support one another by nutrients oxygen or
water...
What is in our Eco –column
Terra Zone; a three leaf clover plant
- it grows very easily and is a green
plant.
; radish seed – supplys oxygen in the system
and germinate quickly.
; Top soil with
fertilizer added – so the plants can survive and contains nutrients for the plants.
; earthworms – Earthworms
move through the ground, recycling dead and decomposing organic material back
into the soil, re distributing nutrients and improving water drainage
Decomposition Zone; a little bit of soil for earthworms.
; apple, banana peel and
granadilla to supply the system with nutrients
; leaves and twigs that
decompose as dead organisms.
Aqua Zone ; ;River water – so it has biotic and abiotic organism in
it and tap water has to many chemicals
in it.
;
algae – to give off oxygen to the water and to observe what will happen to the
algae
