The algae, walleye pollock, and orca populations could have all affected the moon jelly population. What additional
evidence do you need to determine which of these populations might have caused the size of the moon jelly population
to increase?

I'd need the data from the population sizes of the algae, walleye pollock, orca, ocean sunfish and sea turtles. And I'd also need water temperature data, levels of dissolved oxygen.

Explanation:

The jellyfish population may have increased because of an increase in phytoplankton. This leads to an increase in

zooplankton; a decrease in walleye pollock, leading to an increase in zooplankton; or an increase in orcas, leading to a

decrease in sea turtles. Sea turtles, being the main predator for keeping the jellyfish population in check.

Also, if there are more red algae, jellyfish polyps have less place to grow. Without it, the polyps can attach itself on every surface.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.
