Question 34 • Science 7 B (M12 25/26 S2)

In which environment would primary succession take place? Select 2 options. an abandoned fielda cooling lava flowan area of bare rock under a glacieran unused farma deserted mine

Answer
A
an abandoned field
B
a cooling lava flow
C
an area of bare rock under a glacier
D
an unused farm
E
a deserted mine

Explanation

Primary succession begins where there is no soil, such as newly formed rock. A cooling lava flow and bare rock exposed by a retreating glacier provide those conditions, so pioneer species must establish before soil can develop. An abandoned field, unused farm, and deserted mine generally already have soil, allowing secondary succession instead.
