Which of these is a biotic factor in a desert ecosystem?

You didn’t list any, but I’ll give you a few examples.

Since biotic factors are living factors, anything that’s alive in the desert would be applicable.

For instance...

- Animals
- Plants

But mostly land animals for obvious reasons.

Hope this helps!

Since a female is both xx chromosome and the male passes down the x chromosome, than the offspring would be female since a female is xx.
