Blog post on updates of Biotic and Abiotic factors in our ecocolumn

Changes in Biotic components of ecocolumn 

Day 1:

Height of [cactus] plant : 7cm .              Number of leaves : 0

Number of worms :  15 (all alive)  

Number of radishes : 4

Number of leaves on radish #1 : 12

Number of leaves on radish #2 : 8

Number of leaves on radish #3 : 7

Number of leaves on radish #4: 11

*NOTE* all leaves present were a healthy green colour

*NOTE* Fruit flies are presently surrounding our ecocolumn in search of food from our decomp zone.

Day 2:

Height of [cactus] plant: 7cm               Number of leaves : 0

Number of worms : 15( all alive )

Number of radishes : 4

Number of leaves on radish #1 :13

Number of leaves on radish #2 :11

Number of leaves on radish #3 :8

Number of leaves on radish #4 :13

*NOTE * we were able to identify the species of fruit fly as the : Bactrocera mutabilis

THE INFORMATION  USED TO IDENTIFY THIS SPECIES OF FRUIT FLY CAME FROM :http://www1.dpi.nsw.gov.au/keys/fruitfly/mutabili.htm

Day 3 :
Height of [cactus] plant : 7.5cm                   Number of leaves : 0
Number of worms present : 16
Number of radishes : 5
Number of leaves on radish #1 : 14
Number of leaves on radish #2 : 11
Number of leaves on radish # 3 : 9
Number of leaves on radish #4 : 15
Number of leaves on radish # 5 : 2

Changes in Abiotic components of ecocolumn


Day 1 :

Room temperature : 28 'C
Temperature of aqua zone : 22'C
PH acidity of water : 5


Day 2 :

Room temperature : 18'C
Temperature of aqua zone : 18'C
PH acidity of water : 5

*COMMENT* The air movement of our ecocolumn is not very good as the columns are generally covered and opening flaps left closed. this became more obvious as water started to collect on the roof of our ecocolumn.


Day 3 :

Room temperature : 30'C
Temperature of aqua zone : 21'C
PH acidity : 5

Observing Abiotic and Biotic components under microscope.

We cannot record the presence of any organism under a microscopic view of a sample of water taken from the aqua zone.
