The phycosphere is the region surrounding an individual phytoplankton cell that is enriched in dissolved organic substrates exuded by the cell into the surrounding water. Which of the following about the phycosphere is incorrect?

		Photosynthetic bacteria use flagella to swim toward the phycosphere to obtain organic carbon nutrients
		Chemotactic bacteria use flagella to swim toward the phycosphere to obtain organic carbon nutrients
		Chemotactic bacteria detect and swim toward the microenvironment around the phycosphere via chemoreceptors of the chemosensing system
		In the increasing concentration of organic carbon in the phycosphere, tumbling frequency is reduced and runs are longer
