Answer: The advantage of being an osmoconformer compare to an osmoregulator is you don't have to use more energy to regulate ion gradients compare to an osmoregulator.
Step-by-step explanation:
An osmoconformer is a marine organisms that maintains its internal environment without spend more energy that is osmotic to the external environment.
An osmoregulator is an organism that regulates it body osmolarity and maintain its internal environment. Its use or spend more energy for this.
