How would an ash cloud from a volcano affect the flow of matter, cycling of energy, and organisms in an ecosystem?

Ash cloud from a volcano can greatly affect so many systems in the earth. The flow of matter is greatly affected by energy because without energy matter does not move. The cloud of valcano affects cycle of energy because it blocks the energy of the sun the enters the earth which will result to reducing temperature. Example of it the erruption of mt. pinatubo in ph, the earth temperature substanctailly reduces. The ecosystem will greatly be affected due to different temperature and different weather pattern that will occur that will be new to the orgnisms.
