Passive transport .

Explanation:

Passive transport is a kind of transport which is used by Paramecium to remove excess water from its cytoplasm. There is a inverse relationship between the contractile vacuole activity and the environmental salt concentration because if there is salty environment, the contractile vacuole did not their function because there is difference in pressure and the water moves outside when there is salty environment. Bursting of paramecium occur if a biological toxin blocked the activity of the contractile vacuole because no excess water moves to outside environment.

this transfer is call conjunction
