Primary producers are the basis for all aquatic and terrestrial food webs. how does the amount of primary production affect community structure? the more energy available from primary producers, the more individuals that could be supported at higher trophic levels in the community the more energy available from primary producers, the more species that could be supported at higher trophic levels in the community primary production has no direct relationship to community structure

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
