Dr. Pringle’s research concluded “that even among herbivores that eat grasses, each herbivore species consumes some plant species that are not eaten by others.” Park managers work to restore or maintain the populations of as many different native species as possible. Park managers at a national park in Africa are planning to relocate three grazing herbivores—buffalo, zebra, and wildebeest—that disappeared during a civil war. Make a plan for how they would use the tools and methods in this Click & Learn to determine when and where each species should be relocated to the park.

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.
