The Roles and Relationships of the producers and consumers.

All animals, most protists, all fungi, and many bacteria are het- erotrophs. Unlike autotrophs, heterotrophs cannot manufacture their own food. Instead, they get energy by eating other organisms or organic wastes. Ecologically speaking, heterotrophs are consumers. They obtain energy by consuming organic molecules made by other organisms. Consumers can be grouped according to the type of food they eat. Herbivores eat producers. An antelope that eats grass is a herbivore. Carnivores eat other consumers. Lions, cobras, and praying mantises are examples of carnivores. Omnivores eat both producers and consumers. The grizzly bear, whose diet ranges from berries to salmon, is an omnivore. Detritivores (dee-TRIET-uh-VAWRZ) are consumers that feed on the “garbage” of an ecosystem. This waste, or detritus, includes organisms that have recently died, fallen leaves, and animal wastes. The vulture shown in Figure 18-8 is a detritivore. Many bacteria and fungi are detritivores that cause decay by breaking down complex molecules into simpler molecules. So, they are specifically called decomposers. Some of the molecules released during decay are absorbed by the decomposers, and some are returned to the soil or water. Decomposers make the nutrients that were contained in detritus available again to the autotrophs in the ecosystem. Thus, the process of decomposition recycles chemical nutrients.

As a result, energy flows through an ecosystem, moving from producers to consumers. One way to follow the pattern of energy flow is to group organisms in an ecosystem based on how they obtain energy. An organism’s trophic (TRAHF-ik) level indicates the organism’s position in a sequence of energy transfers. For exam- ple, all producers belong to the first trophic level. Herbivores belong to the second trophic level, and the predators belong to the third level. Most terrestrial ecosystems have only three or four trophic lev- els, whereas marine ecosystems often have more. Food Chains and Food Webs A food chain is a single pathway of feeding relationships among organisms in an ecosystem that results in energy transfer. A food chain may begin with grass, which is a primary producer. The chain may continue with a consumer of grass seeds—a meadow mouse. Next, a carnivorous snake may kill and eat the mouse. A hawk then may eat the snake, as shown in Figure 18-9. The feeding relationships in an ecosystem are usually too com- plex to be represented by a single food chain. Many consumers eat more than one type of food. In addition, more than one species of consumer may feed on the same organism. Many food chains inter- link, and a diagram of the feeding relationships among all the organisms in an ecosystem would resemble a web, as shown in Figure 18-10. For this reason, the interrelated food chains in an ecosystem are called a food web.
