How will an organism be benefited if it reproduces through spores?

Following are the ways through which an organism will be benefited if it reproduces through spores:

• Number of spores produced in one sporangium would be large.
• In order to avoid competition at one place, spores can be distributed to faraway places with the help of air.
• In order to prevent dehydration under unfavorable conditions, the spores are covered by thick walls.
