2. QUESTION Round:Time: 2 minutesStandard/Category: Biology QUESTION: Because most animals trawled from the deep sea floor arrive on deck dead, lebenspurren, the “life traces” in deep-sea sediments, were some of the first clues researchers had in trying to deduce the behavior of these animals. Which animals are responsible for many common lebenspurren remains a mystery to this day! 1)Draw a line from each animal on the left to its most likely trace on the right (2 points for each correct match). 2) Identify the animals. You will receive 1 points for each correctly identified phylum, and 2 point for each correctly identified class (or order, if class is not used by modern taxonomists). Common names are acceptable.
