succession case study
the big island of hawaii
the big island of hawaii is the largest
island in the hawaiian archipelago.
there are two active volcanoes on the
island: kilauea and mauna loa. when
these volcanoes erupt, the island
grows in size.
as lava from an eruption flows into
the ocean, new land is formed.
between may and july 2018, 875 acres
were added to the island because of
a major eruption. as weathering
breaks down the rock to form soil, new
plant life will grow on this new land.
2018 british columbia wildfires
in 2018, a total of 2,092 wildfires burnt
3,338,770 acres of land in british
columbia. this was the worst wildfire
burn-area in a british columbia
wildfire season.
wildfires kill most vegetation and
animals that are unable to flee. the
nutrients from the vegetation and
animals return to the soil in the forest.
new plants can grow again in the
nutrient - rich soil.
is the hawaii case study an example
of primary or secondary succession?
why?
is the british columbia case study
an example of primary or
secondary succession? why?

Explanation:

Answer:

Hawaii: Primary succession. No soil existed before (volcano erupts, new land with no soil).
British Columbia: Secondary succession. Soil remained (wildfires kill vegetation but soil is still there).
