During the eruption, hot ash and pumice poured down the west, south, and east sides of the mountain, melting the snow and ice at the top of the volcano and creating volcanic mudflows. Which type of change was seen in the ecosystem around Mount St. Helens after it erupted?a. primary succession b. secondary succession c. a climax community d. species extinction

Correct answer is option "a"

Explanation:

Succession is a directional non-regular total change in the sorts of plant species that involve a given region through time. It includes the procedures of colonization, foundation, and annihilation which follow up on the taking an interest plant species. Most successions contains various stages that can be perceived by the assortment of species that overwhelm by then in the succession start when a zone is made in part or totally without vegetation due to an unsettling influence. Some basic instruments of unsettling influence are fires, wind storms, volcanic emissions, logging, environmental change, extreme flooding, sickness, and irritation. Succession stops when species organization changes never again happen with time, and this community is said to be a peak network.So, the correct answer is option a "primary succession"

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
