Answer: 2) secondary succession
Explanation:
Ecological succession is the change in the biotic community of the ecosystem due to the changes occurring in the abiotic components such as water, soil, atmosphere and others. These changes occur with respect to time until the ecosystem attains the stability.
A secondary succession can be define as the changes which occur after a catastrophic event or ecological disturbance. Such changes brings stability with the help of precursors of previously existing species at the same place.
According to the given situation, secondary succession could have occurred this is because of the fact that the forests fire can burn the vegetation in an area. The burn sites will regrow into a healthy forests because of some of the precursors of previously existing plant species like seeds, stem, roots and others which will help in regrowth of new plants.

Answer:
abyssal clay is not an example of biogenic sediments .
Explanation:
Any sediment containing more than 30% of organic matter in it , is called as biogenic sediment or biogenic ooze.
The two most common types of biogenic oozes are calcareous and sileceous.
abyssal clays are the fine grained sediment particles that are settled in the deep ocean basins.
abyssal clay mostly consists of land derived eroded particles and have less than 30% of organic matter in them ,
Hence , abyssal clay is not an example of biogenic sediment.
