Match the following: Set-I Set-II (A) Endosmosis (I) High altitude adaptation (B) Exosmosis (II) Desert adaptation (C) Metabolic water (III) Problem for fresh water animal (D) Increase in the RBC production (IV) Problem for marine animals The correct match is

A = III , B = IV , C = II , D = I

A = I , B = III , C = IV , D = II

A = II , B = III , C = IV , D = I

A = III , B = II , C = I , D = IV

Organisms that prepare their own food from simple inorganic compounds present in their environment are called autotrophs and the mode of nutrition is called as an autotrophic mode of nutrition. For example- green plants. There are two types of autotrophs- photoautotrophs and chemoautotrophs.
