Food Chains is a great book for kids and adults. The format is very organized and a bunch of interesting facts. I thought this book was going to be all about charts and numbers but I was totally mistaken. This book has tons of useful facts and only a few charts! Did you know every bite the blue whale takes, it swallows over a million krill? Or did you know that a kangaroo rat is related to a mouse, and is neither a kangaroo or a rat? I loved everything about this book and I recommend it to all nature/animal lovers.
