2 Which of the following is an example of an abiotic factor?
A) Oak tree
Mushroom
C) Dead, broken branch
D Sand particle

I’m guessing D a sand particle

D) sand particle because an abiotic factor is something that isn’t alive like temperature but in this case an oak tree is living and a dead branch was once living for which it’s an biotic factor so your answer is a sand particle which isn’t living nor will ever be living
