1. Scenario: (A) The salt marsh suddenly becomes very hot (close to 100F) for 3 days in a row Suggest how the following abiotic factors might change and explain your reasoning. (Circle and provide explanation.) (8pts) increase decrease no change Water temperature @ Mosquito Ditchincrease decrease no change Scenario: (B) The salt marsh just gets heavy rain (water content increased temporarily in salt marsh). How the following abiotic factors might change and explain your reasoning. Water pH @ Rocky Beach decrease no change increase Conductivity @ Rocky Beach increase decrease no change

Explanation / Answer

As temperatures increases solubility of oxygen in water decreases. So dissolve oxygen decrease.

Water temperature increases due to rise in atmospheric temperature

Rainfall is slightly acidic due to reactions with CO2 to form carbonic acid in the atmosphere. So rainfall decrease the water ph.

Rainfall decrases the conductivity of water bodies because rainfall dilute their salinity and concentration.
