Answer 1

Animal that contains formic acid - ant

Plant that contains formic acid - nettle plant

Answer 2

The animal and plant whose stings contain formic acid are ant and nettle respectively.

Explanation:

The Latin word used for ants is “Formica”, this is from where the word 'formic acid' is originated. Ant species release a venom spray from the "end of their abdomens", the "venom contains formic acid".

Similarly, plant species like nettle, their end of the leaves are converted to stings because when comes in contact with the skin, it pierces the skin, and inject formic acid into it. Formic acid is acidic in nature. A base will neutralize it.
