Populations Lab Report Instructions: The Virtual Populations Lab is on the lesson assessment page. Gather data to
evaluate Sebastian's Snorkel Spot's claim that a new factory is polluting the coral reef. Follow
the instructions as you move through the lab and record your data and observations in the lab
report.

Procedure
During the research phase, you found that the factory is not using nutrient-removal treatment on
the water it releases. Excess nutrients in the water encourage algae growth, which can smother
coral. To monitor the water quality and health of the coral reef, you will collect data on five
factors: water clarity, dissolved oxygen levels, percentage of live coral coverage, number of
juvenile parrot fish observed and number of mature parrotfish observed.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
