1. Coral reefs are among the most spectacular ecosystems on Earth. They support a rich diversity of life and provide economic benefits to the people who use them. In Papua New Guinea in the Pacific Ocean north of Australia, the following data were collected. Coral cover is the percentage of the reef surface covered by living hard coral. It’s represented by the dark dashed line on the graph. Calculate the difference in coral cover between 1996 and 2002. HINT: “Difference” in math means that you subtract.

To calculate the difference in coral cover between 1996 and 2002, you would need the specific coral cover percentages for those years from the graph you mentioned. Since I cannot see the graph, I cannot provide the exact difference.

However, to perform the calculation, you would subtract the coral cover percentage for 1996 from the coral cover percentage for 2002:

Difference = Coral Cover (2002) - Coral Cover (1996)

If you provide the actual coral cover values for those years, I can help you calculate the difference.
