Young readers are introduced to: -- the relationships that exist between groups of organisms and their environment-- important ecological concepts, such as producers, consumers, decomposers, and food webs, explained and illustrated with examples-- activities that encourage children to investigate ecosystems closer to home-- tips on observing safely without disturbing nature or endangering themselvesVisit the rocky shores of A Tidal Pool and find out about seaweed, shells, and the diverse number of animals that make tidal pools their home.

A trip to a tidal pool outlines rules for observing nature without endangering creatures, plants, and young observers.Concepts are explained such as: -- food chains and webs-- camouflage-- breeding-- survival in a constantly changing coastline
