Answer:
Pioneer organisms are ound predominantly in:
a) primary succession
Explanation:
The correct answer is disasters because Primary succession is the concept to identify a region in which vegetation and no plant-based organisms grow over time in a place that is characterized by the absence of soil. The development of these ecosystems takes a great amount of time due to the difficulty of growing without soil. The rest of the options are wrong because none of them talks about the exact moment after a disaster deprived a zone of soil and elements to sustain regular organisms.
