Pea plant clones are giving different amounts of water for three-week period. The first pea plant receives 400ml a day. The second pea plant receives 200ml a day. The third pea plant receives 100ml a day. The fourth pea plant does not receive any extra water: the plant only receives natural ways of receiving water. The heights of the pea plants are recorded daily.
Identify the variables
