What are two alternatives to biological parenthood what is the difference between the two?

Two alternatives to biological parenthood are adoption and surrogacy. Adoption involves legally taking on the parenting responsibilities of a child who is not biologically related, often from the foster care system or through private agencies. Surrogacy, on the other hand, involves a surrogate mother carrying a child for another individual or couple, who may or may not be the biological parents, through either traditional or gestational methods. While adoption creates a parent-child bond through legal and emotional means, surrogacy focuses on the gestational process and can involve biological ties to one or both intended parents.
