microorganisms are nonliving and the ecological succession changes the abiotic parts in an ecosystem.
Andrea. I hope you're not taking an online class. You need a lot of help from a teacher you can sit down and talk with. Obviously, trying to get help from an online teacher didn't work for you.

Microorganisms are living.

You didn't tell how the ecological succession changes the abiotic parts.

Good night -- and good luck!
