In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are the amount of water and temperatures. Terrestrial ecosystems rely on the sun's energy to support the growth and metabolism of the organisms. Plants use the sunlight, then they supply the organisms that are higher up the food chain with energy and the structural buildings blocks of life. Water is also essential for the survival of these organisms.
The right answer is excess carbon dioxide.
For a cell to do a photosynthesis, it needs.
chloroplast
water (providing hydrogen and oxygen)
Carbon Dioxide (Providing Oxygen and Carbon)
And finally the sunlight.
This will produce, oxygen and glucose, two essential elements in animal life.
The eruption of Mt. St. Helens is considered to be one of the worst destructions that is ever recorded in the United States. The entire seemed to have become a barren and lifeless space however, there are still a few plants who survived from the hot rocks coming from the volcanoes.

They became the pioneering life in reconstructing and reforming the landscape of the area.
A whole number ratio; Hopefully that is the answer if you need an actual number the best guess would be 2:1.
