mollusks take in water from its environment and then extract the oxygen from the water to breathe. by the way it is through not threw :)
To exchange water for oxgen. They are technically located near its stomache.
These two shelled mollusks have 2 pair of gills to get oxygen.
Well land mollusks live on land usually, and water mollusks live underwater. Neither can survive in the others enviroment. I think..
Mollusks breathe in water primarily through gills, which are specialized organs located in their mantle cavity. These gills extract oxygen from the water as it flows over them, allowing for gas exchange. In some species, water is drawn in and expelled through siphons, enhancing efficiency in respiration. Additionally, some terrestrial mollusks have adapted to breathe air using a modified lung-like structure instead of gills.
They live in water.
Because they suck in water and filter food particles out of it.
through their open circulatory system
The mantle excretes the calcium carbonate to make the shell of the animal... (Among other things...) By the way chap, lungs don't extract oxygen from water...
Can detect polluted water
Most are in water.
No, they don't.
