Final answer:
Osmoregulators actively control osmotic balance by using energy to maintain osmotic gradients within their bodies. They achieve this through processes such as active transport.
Step-by-step explanation:
Osmoregulators are animals that actively control the osmotic balance within their bodies by expending energy. They utilize various mechanisms or processes to achieve effective osmoregulation. One important mechanism is active transport, which requires the use of ATP molecules to move solutes against concentration gradients. By actively regulating the movement of water and solutes, osmoregulators maintain osmotic gradients and adapt to different environments.
