The ecology in the school farm
Chene Mohammed
To study a manmade ecological system at Couva Government is Secondary School, Tlinidad (the manmade ecological system the school)

The main ecological systems in the fatm arc;
(a) pond ecology

(which include fruit trees)
The ecology studied will be compared to similar, natural ecosystems'
@) ecology of the evergreen trees

The main objective: Adaptation, Species diversity'
(1) is to study Charles Darwin's theory on

(a) Natural selection
(b) AdaPtation
(2)Thefarm,sbiogeochemicalcyclesandcomparethemtonaturalcycles
(3) Competition-( fish species and trees)
(4)Speciesdiversity(thefishesinthepondandthefarmtrees)
(5) Growth rate (fishes in the Pond)
