Biodiversity in the ocean is critical to the health of the planet, yet very few texts are available that explain the variety of aquatic food chains. Through appealing photography, clear text, and engaging design, Ocean by Sean Callery examines one lifecycle in each of three oceans-The Indo-Pacific Ocean, The Pacific Ocean, and the Atlantic/Indian Ocean. At the end the three cycles are woven together into one food web, demonstrating that all life in the ocean is linked. A wonderful introduction to an environmental topic that is at the forefront of current events.<br />Each book in this essential series reveals the life cycles of ten animals in a particular habitat which link together to create three food chains. At the end of the book a simple overview helps readers understand how the three food chains interact to create a food web- the perfect first introduction to this core science concept.
