Based on Jill's observations, which conclusion could you draw?
1) The warm water and abundant sunlight in the neritic zone limits the plankton population.
2) Organisms in the benthic zone must be able to tolerate large amounts of oxygen.
3) There are no producers in the benthic zone that rely on photosynthesis.
4) Organisms in the intertidal zone must be able to withstand very cold water.
