subtitle zone -marine algae, seaweed, killifish, salt fish(well adapted)

Intertitle zone -tall grass(hollow for respiration) -fragile in spring -salt water grown -shells at surface -fiddler crabs - salt marsh acrs as filtering device (rain water, oil, pesticides broken down at salt marshes) - salt marshes are nurseries for other systems

 * Transect**

1 drop of thiosulfate (.05ml) 8 drops starch indicator to turn blue/purple 1 drop of thiosulfate (.05ml) to turn color back to clear
 * Light**

out solution was already very diluted, when we added 1.0ml of thiosulfate it made our water too diluted and when we added the starch indicator it did not turn blue. We repeated this procedure about three times until we can to the conclusion to use as little thiosulfate as possible. When we added one drop which is .05 ml of thiosulfate our water turned blue.
 * Limits**

1 drop of thiosulfate (.05ml) 8 drops starch indicator to turn blue/purple 1 drop of thiosulfate (.05ml) to turn color back to clear
 * Dark**

We already knew the solidity of our water after the light test, so we knew to only __use .05ml of thi__osulfate, however the first trial did not work so we had to repeat our experiment until it turned blue.

-10 drops was too much, it didnt turn the water yellow, but clear, so we used less we used .6
