What is a disadvantage for organisms that reproduce asexually rather than sexually?

A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilized by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage.

Explanation:

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
