Answer:

Poisoning caused by the mushrooms like by eating Amanita phalloides can lead to the death of the organism after a few days. The chemical α- amanitin causes serious problems to humans as it shows its effect by inhibiting the RNA polymerase II enzyme which acts during the formation of mRNA.

If mRNA will not be formed, therefore the process of protein synthesis will not take place as a result, all the cellular processes will be halted and the organism will die.

The organisms do not die frequently after consumption of the mushroom instead dies few days only when the α- amanitin starts showing its effect on the liver and kidney and the liver and the kidney fails to perform their work.

Since the liver and kidney fails after a few days by the chemical α- amanitin, therefore, the organism dies after a few days.
