Answer:
B) ecological succession
Explanation:
The analogy given in this question describes ECOLOGICAL SUCCESSION, which is the series of changes that an ecosystem undergoes over a period of time. Ecological succession is of two types viz: Primary succession and Secondary succession.
Primary succession involves the series of changes that occurs on a new habitat that has never been previously colonized. This is the case of the colonization of bare rocks with no plant life by LICHENS. The action of the lichen, which involves secretion of acids that disintegrates the rocks into soil, paves way for the colonization of that area by new species.
Lichens, via the role they play in primary succession by helping alter a barren area into a fertile one that accommodates other organisms, makes them be regarded as PIONEERS of primary succession.
People with central sleep apnea experience a complete cessation of respiratory activity for brief periods of time yet do not have frequent awakenings and do not tend to feel tired during the day.
<h3>What is sleep apnea?</h3>
Breathing regularly stops and starts during sleep, which is known as sleep apnea. People may have sleep apnea if they snore loudly and still feel exhausted after a full night's sleep.
These are the primary forms of sleep apnea:
The more prevalent type of obstructive sleep apnea happens when throat muscles relax.
Central sleep apnea, which develops when your brain fails to properly activate the breathing muscles,
When a person has both central and obstructive sleep apnea, it is known as complex sleep apnea syndrome, also called treatment-emergent sleep apnea.
