Chapter 34, Problem 10TYU
Summary Introduction
To explain:
The reason that giant insects are improbable.
Introduction:
The largest insects known till now existed in the Paleozoic era. These were Paleozoic dragonflies with a wing span of half a meter. However, movies like Godzilla have shown creatures with several dozen meter wing spans. These giant insect creatures are improbable to exist.

Your graphs should have helped you learn about relationship between size and respiration; what is true?
a. Respiration per gram of weight is higher in smaller animals.
b. Respiration per gram of weight is higher in large animals.
c. Respiration per gram of weight is the same for animals of all sizes.
EVOLUTION CONNECTION One opponent of the moviemonster Godzilla is Mothra, a mothlike creature with awingspan of several dozen meters. The largest known insectswere Paleozoic dragonflies with half-meter wingspans. Focusingon respiration and gas exchange, explain why giant insects areimprobable.
Animals breathe in air that contains more oxygen than the air they breathe out. Where is oxygen consumed?
