The Science of Living Things series helps children understand that they are as connected to trees, rocks, and weather as the animals that live outdoors This important series helps define the basic concept of life and investigates the incredible world of living things. Each book explores a basic scientific concept or animal using: -- easy-to-understand text-- clearly labeled diagrams-- exciting, full-color photographsSunlight does not go very deep into water so seaweed must grow at the surface where its rays can reach them. Starting with the sun, food chains link together plants and animals in various ecosystems to help them survive. What are Food Chains and Webs? describes these connections in a clear manner that children will understand. Fascinating diagrams show children: -- the connection between herbivores, carnivores, scavengers, decomposers, and themselves-- concepts such as energy pyramids, photosynthesis, and consumer hierarchies-- an entertaining food web game
