The Web of Life all living things in the woods or meadow depend on others for their food. Each, in turn, is food for other species. Dead leaves and animals are an important source of food for “de­composers “. Worms, for example, eat dead leaves and help make the soil fertile. In turn, they provide food for birds and mammals. Big predators are in no danger of being eaten themselves - at least no while they are alive. But when animals die their bodies provide food for scavengers, such as the larvae of flies and carrion beetles, which eat dead flesh. What remains slowly rots back into the soil where it provides nutrients for plants. At the same time, there are vast numbers of leaf-eating animals in the woods, such as caterpillars, red squirrels, field mice and fallow deer. In nature nothing is wasted, so animals at the end of the food chain will eventually supply food for plants at the beginning.
