Question

which type of ecological succession is shown here?
tertiary succession
primary succession
secondary succession
none of these

Explanation:

The image shows a rocky, mountainous area with snow, likely a newly exposed or barren environment (like after glacial retreat or volcanic rock exposure). Primary succession occurs on lifeless, newly formed/ exposed substrates (no soil, just rock/mineral deposits). Secondary succession is on disturbed areas with soil, tertiary isn't a standard ecological succession type. So this fits primary succession.

Answer:

B. Primary succession
