What Must Freshwater Fish Do to Maintain Homeostasis

Question

What must freshwater fish do to maintain homeostasis?
A)excrete large quantities of electrolytes
B)consume large quantities of water
C)excrete large quantities of water
D)take in electrolytes through simple diffusion
E)change the concentration of electrolytes in their blood

Accepted Answer

Freshwater fish need to excrete large quantities of water to maintain homeostasis because they live in a hypotonic environment, where water constantly enters their bodies by osmosis. This excess water needs to be eliminated to prevent the fish from swelling and potentially bursting.
