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

Answer 1

Answer: The question is incomplete, the image is not given.

Option B is the answer.

Primary succession after volcanic eruption.

Step-by-step 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.

Answer 2

b. primary succession after a volcanic eruption

Step-by-step explanation:

The image (see the attached image), represents primary succession after a volcanic eruption.

Succession general refers to the process of gradual change in the species composition of a community over a long period of time. There two types of succession:

1. Primary succession: This represents a change that occur on a new site that has not held any previous community before. New species that colonize such sites are referred to as pioneer species.
2. Secondary succession: A kind of changes that occur after a community has undergone a disturbance regime.

Both primary and secondary succession eventually lead to a relatively stable community (climax community) in the long run if there are no incidence of disturbance.

The image represents a site that has just witnessed a volcanic eruption. the newly formed site has no history of any community of organisms before. Species of organisms found growing on this site are the pioneer species. Hence, this kind of succession is primary.

The correct option is b.
