b) primary succession after a volcanic eruption
c) secondary succession after a controlled fire
d) secondary succession after a volcanic eruption

The question is incomplete, the image is not given.

Option B is the answer.

Primary succession after volcanic eruption.

Explanation:

Primary succession occur when new land are formed from an habitat that has not been colonized before. It occurs when a disaster like volcanic eruption occur in a place and takes the soil. It is characterized by regions with absence of soil and living organisms. Primary succession start with pioneer species like lichens , algae and misses that can grow on bare rocks.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
