Short summary
We question here is whether phytoplankton community growth rates respond to nutrient concentration in a similar manner to phytoplankton species composing the community, that is, following Monod's model. In situ marine community growth rates in relation to nutrient concentration and the behaviour of a simple multi-species community model show that community growth rate does not follow Monod's model. We observed here that this can be explained as a consequence of change in size structure.
