Students explore how plants use energy from the Sun to produce matter and how the energy and matter stored in plants are transferred to consumers within a food web. They also learn that all the energy within an ecosystem can be traced back to the Sun.

Students build representations of food chains with paper rings and connect them together to form a food web. Teaching tips are included.

The book Food Chains and Food Webs helps readers explore how living things are interconnected. It classifies organisms in several ways based on how they receive the matter and energy they need to grow, live, and perform activities. Organisms can be described as producers, consumers, or decomposers. Special species such as scavengers and parasites also play an important role in ecosystems. The book introduces food chains, food webs, and energy pyramids as graphical devices that can be used to demonstrate connections within an ecosystem. By visualizing the interconnectedness of species within an ecosystem, one can observe and understand population patterns, competition, and why each species has the adaptations it does. Finally, the book explains natural and human-caused ways that ecosystems can change.
