Food Webs
by Carol Ballard (9781615323517)

A food web, which is more complex than a simple food chain, is a model that shows all the possible feeding relationships between organisms that are living within an ecosystem. Because most organisms depend on more than one species for food, food webs are more accurate models than food chains. This book presents food webs and how they chart the natural processes of survival. Students will gain a foundational understanding about the transfer of energy from species to species.
