WebbPhytoplankton are tiny, photosynthetic organisms. This means they can manufacture their own food using energy from sunlight, producing oxygen as a by-product. They are often referred to as tiny plants because of this ability to photosynthesise, but many species of phytoplankton are more closely related to protists and bacteria than true plants. Webb12 sep. 2012 · Abstract. The classic portrayal of plankton is dominated by phytoplanktonic primary producers and zooplanktonic secondary producers. In reality, many if not most plankton traditionally labelled as phytoplankton or microzooplankton should be identified as mixotrophs, contributing to both primary and secondary production.
