Scenario #3
Sea grasses grow on the ocean floor in shallow areas. Runoff from the land into the ocean can cause the waters to
become cloudy, or turbid. As a result, light cannot reach the seagrass growing on the bottom.
What will most likely happen to the seagrass population? Explain using the concepts of range of tolerance and abiotic
factors.
What will most likely happen to the populations of animals, like the manatee, that depend on
seagrass for energy? Explain using the concepts of range of tolerance and abiotic factors.
