Explanation:
Standard reduction potential is the tendency for an element to gain electrons or get reduced ,measured at standard conditions i.e. when concentration is 1 M and temperature is 298 K.
It is given by:
Thus lithium has the lowest tendency to accept electrons and thus has lowest standard reduction potential.
Because energy is wasted as heat, there is less energy available as food for organisms at each level above so ecological pyramid is smaller at the top than the bottom.
