Frogs eat flies, snakes eat frogs, and hawks eat snakes. What would happen to the frogs if the hawk population suddenly decreased?
A. The frog population would increase.
B. The frog population would decrease.
C. The frog population would stay the same.
D. The frog population would increase at first, then decrease as hawk populations recovered.

the frog population would decrease

Explanation:

the snake population would increase because the predator will have been reduced thus giving ample time for the snake to reproduce increasing in population and the number of predators to the frog will increase thus reducing in number

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
