This document discusses animal habitats, adaptations, food chains, and food webs. It defines key terms like producer, consumer, decomposer, herbivore, carnivore, and omnivore. Examples of animal adaptations include structural adaptations, behavioral adaptations, camouflaging, mimicry, and hibernation. Food chains show the transfer of energy as organisms eat each other, starting with producers and moving through primary, secondary, and other consumers. Decomposers break down dead remains and release nutrients.
