Food Chains and Food Webs

The book Food Chains and Food Webs helps readers explore how living things are interconnected. It classifies organisms in several ways based on what they eat or how they receive the energy they need to live and perform activities. Organisms can be described as producers, consumers, or decomposers. The consumers can be classified as carnivores, herbivores, and omnivores. Consumers can also be described as being predators or prey, and sometimes both. 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.
