complete the passage with the words that make the most sense.
dormancy sedimentation germination symbiosis
in 1980, after over a century of inactivity, an earthquake shattered mount saint helenss
, triggering an eruption much more powerful than an atomic bomb. over
230 square miles of the surrounding landscape were devastated with ash and debris,
resulting in an inhospitable wasteland called the pumice plain. and yet, amid the
devastation, a humble wildflower called the prairie lupine managed to take root. through
with special bacteria called rhizobium, the plant was able to draw much-
needed nitrogen from the air and survive where other vegetation could not. these flowers
created a foundation that drew pollinators and helped other plants grow, the beginnings of a
near - miraculous recovery.

Explanation:

The first blank: "dormancy" means a state of inactivity or rest. Since the volcano was inactive for over a century, "dormancy" fits.
The second blank: "symbiosis" is a close and long - lasting interaction between different biological species. The prairie lupine and Rhizobium bacteria have a symbiotic relationship (the plant gets nitrogen from the bacteria).

Answer:

The first blank: dormancy.
The second blank: symbiosis.
