C, N, S, P, H and O are essential components of biomolecules which are present in living organisms. Carbon (C) comes through photosynthesis and nitrogen (N) is obtained through nitrogen-fixing bacteria. Sulphur (S) and Phosphorus (P) are absorbed from the soil. Hydrogen (H) and oxygen (O) are obtained by water. Living forms also take up oxygen through inhalation of air. These nutrients are obtained by animals when they take food either directly or indirectly from plants.
