Question

Imagine a newly created barren land made of igneous rocks. Some new species came, colonized and grew in this rocky area. What kind of succession pattern did this species follow?

(a) Secondary succession

(b) Climax succession

(c) Primary succession

(d) Tertiary succession

I have been asked this question at a job interview.

This intriguing question comes from Ecological Succession in section Ecosystem of Biology – Class 12

Answer 1

Right answer is (c) Primary succession

To elaborate: The species in the above example follow a primary succession. A biological succession (growth of living organisms) occurring on a previously unoccupied or bare land is known as primary succession.
