Chapter Review Jeopardy THANK YOU for PLAYING!!! Know complete and incomplete metamorphosis phases – be able to contrast them – give examples of organisms. Would you like a final Jeopardy question?

Final Jeopardy What characteristics of arthropods may have allowed them to become the most numerous type of animal on Earth? Possible answer: Arthropods have exoskeletons, which help to protect their organs. Many arthropods have protective devices to defend themselves, such as large claws, stingers, or mouths that bite. Most insects have wings and many insects are small, which makes them more difficult to catch or kill. Many arthropods have colorings that help them blend in with their environment. Also, arthropods usually reproduce at a faster rate than other animals.
