OVERVIEW This worksheet complements the short video “Steve Palumbi and Megan Morikawa Study Coral Reef Damage in American Samoa” from the Scientists at Work series. PROCEDURE 1.Prior to watching the video, read the questions below. 2.Watch the video. 3.Answer the questions. 4.When finished, save as a pdf and upload this document to D2L. QUESTIONS 1.Provide two examples of why coral reefs are important ecosystems on Earth. 2.Corals form symbiotic relationships with microscopic photosynthetic algae that live in their cells and give the corals their distinct colors. The relationship is an example of mutualism, in which both species benefit. Predict how each organism in this relationship could benefit the other. 3.Heat stresses coral communities and can lead to coral bleaching. What is the impact of long-term coral bleaching to an individual coral? To a coral reef? 4.Some corals in the warm pools off Of Island can withstand temperatures of 32° to 34 °C without bleaching. So, the researchers set up a controlled laboratory experiment to try to determine why these corals survive in such excessive heat. With regard to the experimental design, provide two reasons why Dr. Palumbi devised a standardized test for the corals.
