Which of the following scenarios accurately describe how succession occurs as a natural process of ecosystem restoration? Glaciers have been slowly melting for hundreds of years in Glacier Bay, Alaska. As the glaciers melt and earth is exposed, mosses and lichen begin to grow. This is followed by larger plants and eventually tall shrubs. Over time, the area is said to reach maturity.
In Indonesia, a rain forest is cleared for urban use. Once trees are cut down, lichen begins producing soil. Afterwards, decomposers are able to move into the area, followed by larger species such as birds and rodents.
In Haulalai, Hawaii, lava from volcano eruptions have covered many portions of the island. Small weeds and native grasses emerge from the lava. Small insects feed on the grasses which attract birds.
In California, a forest fire grows out of control. Once the fire is extinguished, seeds that were able to survive the fire begin to sprout. These seeds die off because there is no soil. The area remains barren.
