Question

the scientists from seafoam island collected a lot of data about seafoam reef over time. they used their data to make projections about seafoam reefs future. a projection is an informed estimate of how an environment will change under certain conditions. the graph below shows one of the scientists projections. this projection shows how the percent seaweed cover, or percentage of seafoam reef covered by seaweed, will change if nothing is done to stop boat anchors from damaging corals. projected percent seaweed cover for seafoam reef according to the scientists projection, which of the following is likely to happen by year 30? select the two best choices. more than 75% of seafoam reef will be covered in seaweed. all of seafoam reef will be covered in seaweed. the area of seafoam reef covered by seaweed will be greater than in year 3.

Explanation:

• For the first option: Looking at the projection line on the graph, by year 30, the percent seaweed cover is above 75%. So, more than 75% of Seafoam Reef will be covered in seaweed.
• For the second option: The projection line does not reach 100% (which would mean all covered). So, the statement “All of Seafoam Reef will be covered in seaweed” is incorrect.
• For the third option: In year 3, the seaweed cover is very low (close to 0), and by year 30, it is much higher. So, the area of Seafoam Reef covered by seaweed will be greater than in Year 3.

Answer:

• More than 75% of Seafoam Reef will be covered in seaweed.
• The area of Seafoam Reef covered by seaweed will be greater than in Year 3.
