🦗 Invertebrate Groups
This quiz explores the eight major invertebrate phyla studied in Grade 6 Biology. You'll examine the defining characteristics, examples, and roles of Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, and Echinodermata. **What you'll learn:** - The key distinguishing features of each invertebrate phylum - Examples of organisms within each group - How these animals are adapted to their environments - The ecological importance of invertebrate diversity
