Pass the Energy, Please! Biologist Barbara Shaw McKinney and illustrated by Chad Wallace.

For kids-- this explains about the cycle of life in the food chain. Even I needed to understand this-- we are now so disconnected from this cycle.

"Passing the energy needed to live, is a difficult thing for a creature to give. But a chain unbroken along the way, links life in the woodland from day to day."

How plants make energy from the sun, and the animals eat the plants, and also about carnivores.

Ends on a note of conservation. My kids love this one, it's a favourite (but I do simplify it for the little ones. "Look out weasel. Here comes fox! Look out, fox...)
