Each organism in a population produces more offspring than can survive. this is called .

Hey there!

It's called biotic potential.

This is because for natural selection to occur, the populations need to have variations.

I hope that helps! :)

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
