Respuesta :
Well the ash would block out the sun, and would stop photosynthesis, which would kill the trees and plants. that would cut off the supply of oxygen, making it hard to get a substantial amount of air for animals.
This event will affect the ability of animals to obtain energy to live through
reduction in the photosynthetic processes of plants.
Plants are the primary producers in the ecosystem and absorb solar energy
from the Sun in order to convert to chemical forms which are used by other
consumers. The consumers depends solely on the producer for food and
energy.
A volcano throwing so much ash into the air and blocking much of the
sunlight will result to a decrease in food and energy production by plants.
This will bring about mass deaths of plants and animals in the ecosystem.
