Decomposers break down dead plants and animals. They also break down the waste of other organisms. They are an important element in the food chain because they keep up a continuous flow of nutrients for the primary producers.Food Chains, Food Webs, and Ecological Pyramids. A food chain is the simplest path that energy takes through an ecosystem. Each level in the transfer of energy is a trophic level. Organisms at each level use energy in cellular respiration and heat loss and store the rest.A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. eg. Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers -- an example is a rabbit that eats grass.A food web is similar to a food chain but larger. The diagram combines many food chains into one picture. The diagram uses arrows to show the energy relationships among organisms. Food webs show how plants and animals are connected in many ways. ... A food web (or food cycle) is a natural interconnection of food chains.A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.The food chain is the pattern that energy uses to transmit to producers to decomposers. A food chain only follows just one path as animals find food. A food web shows the many different paths plants and animals are connected. A food web is several food chains connected together.
