Question

which of the following occurs after tsunami and forest fire? primary succession quaternary succession intersitary succession tertiary succession

Explanation:

After a tsunami and forest fire, the ecosystem starts to recover. Secondary succession occurs in an area where a disturbance (like fire or tsunami - related destruction) has happened but soil and some organisms still remain. Primary succession is for barren areas with no soil. Quaternary and tertiary succession are not standard ecological succession stages in this context. So secondary succession is the correct answer.

Answer:

Secondary succession (assuming the option with "Secondary succession" is the correct one; since the text in the options is a bit unclear due to image quality, but based on ecological knowledge, the correct option related to secondary succession is the answer. If the options are:

• Primary succession
• Quaternary succession
• Secondary succession
• Tertiary succession

Then the answer is: Secondary succession (the option with "Secondary succession" text, e.g., if it's the third option, then "C. Secondary succession" assuming the options are labeled C for the third one, but need to match the actual option labeling in the original question. Since the image text is blurry, but from the context, the correct concept is secondary succession.)
