(i) Many of the respiratory poisons (Malonate etc) also inhibit water absorp­tion.

(ii) KCN which reduces metabolic activates also reduces water absorption.

(iii) Respiratory promoters increase the rate of absorption (e.g. hormones).

(iv) Low temperature, which retards the rate of energy release during res­piration also, reduces water intake.

ADVERTISEMENTS:

(v) Aerobic conditions are necessary for water intake.
