5. In the table below are simulated data of net photosynthesisrate for five replicate leaves from two plant species, sawgrass(Cladium jamaiscence) and willow (Salix caroliniana). Using thedata below and the ‘Analyzing Ecology’ box in Chapter 2 of the text(pg 42), calculate the mean (x), variance (s¬2), standard deviation(s), and standard error (SE) for the two pH conditions. Construct agraph using the means and standard deviations to visually comparephotosynthetic capacity between the two species. Make sure to labelyour axes appropriately and indicate which is the dependent and theindependent variable.
Table 1. Photosynthesis rate (µmol CO2 /m2 / sec) for sawgrass and willow leaves.
Replicate | Sawgrass | Willow |
1 | 6.4 | 8.0 |
2 | 6.1 | 8.4 |
3 | 6.8 | 7.7 |
4 | 6.3 | 8.1 |
5 | 6.3 | 7.9 |
