What's the difference between osmoconformers and osmoregulators?
Osmoconformers maintain a constant internal osmolarity, while osmoregulators have an internal osmolarity that changes with the terrain.
Osmoregulators maintain a constant internal osmolarity, while osmoconformers have an internal osmolarity that changes with the terrain.
Osmoconformers maintain a constant external osmolarity, while osmoregulators have an external osmolarity that changes with the terrain.
Osmoregulators maintain a constant external osmolarity, while osmoconformers have an external osmolarity that changes with the terrain.
Osmoconformers are creatures whose internal osmolarity changes in relation to their external terrain, while osmoregulators are creatures who can maintain their internal osmolarity at a particular position anyhow of the external terrain. Hence, option 2 is the correct answer.
