In many parts of the Everglades in Florida, excessive irrigation is lowering water levels and allowing salt water to enter the freshwater swamps. Why is this a problem for plants that have adapted to life in these swamps?

A. Photosynthesis is inhibited by salt.
B. The plant roots cannot take up water if the soil salt concentration is high.
C. The salt competes with minerals for uptake by the plants, limiting their growth.
D. The plants cannot move sugars down the xylem if there is salt outside of the roots pulling water out.
E. Salts bind to nitrogen, preventing it from being taken up.


B. The plant roots cannot take up water if the soil salt concentration is high.

You notice mayfly larvae trying to emerge from a stream being slowed down when they reach the surface. Why might this be?

A) Because of the surface tension of the water. B) Because of the colder temperature at surface. C) Because of less oxygen at the surface. D) Because of higher flows at surface.
