An experiment was carried out to determine the growth rates of bamboo and a variety of maize plants in two adjacent plots. The average heights and average dry weight of plants from the two population were determined over a period of twenty weeks. The data is as shown in the table below.
(a) Between which two weeks did the greatest increase in weight occur in
(i) Bamboo
(b) (i) Which of the two types of plants had a higher productivity by the end of the experiment?
(ii) Give a reason for your answer in (b) (i) above
(c) Between weeks 14 and 18, the average height of the maize plants remained constant while average dry weight increased. Explain this observation.
(d) Suggest how the change in average dry weight of bamboo and maize plants would have been at week 22 if
the experiment was continued.
(e) Why was it appropriate for this experiment to use.
(i) Dry weight instead of fresh weight
