Biology Unit Final Assessment- by . Earth Think, We Need Your Help!. My name is Michelle Geiszler, and I am an ecologist studying various ecosystems to ensure that all populations and species are still capable of survival. I recently discovered that the Black footed ferret is endangered! I have created a PowerPoint presentation for you that will hopefully have you considering how important this species is to the environment, and without it, it’s ecosystem could collapse! Please consider helping this amazing species with its survival. Thank you for your time and consideration. I hope you enjoy learning from this presentation. . 1. Phylum Annelida. Class Polychaeta.
