Why are diverse relationships observed between phytoplankton biomass and transport time?

为什么浮游植物生物量和输移时间的关系五花八门？

The results showed that bacterial growth was positively correlated to water temperature. COD and zooplankton biomass, but it did not directly correlated with phytoplankton biomass.

研究表明，池塘细菌的生长与COD、水温以及浮游动物的生物量呈正相关，而与浮游植物的生物量相关性不十分明显；

Scientists use these changes in ocean color to estimate chlorophyll concentration and the biomass of phytoplankton in the ocean.

Furthermore, multi-decade time series, including the Hawaii Ocean Time Series, the Bermuda Atlantic Time Series, and the California Cooperative Oceanic Fisheries Investigations, also showed increasing phytoplankton biomass during the past 20-to-50 years.

There have been some unexpected responses, for instance markedly different phytoplankton communities and total biomass resulted from two iron addition experiments conducted a year apart at the same site in the north west Pacific Ocean.
