The food chain is comprised of various types of organisms: those who produce, those who consume, and those who decompose. Consumers are grouped into various trophic levels and energy flows from the top trophic level to the lower one. This is called the secondary consumer and is dragonfly larvae in the above food chain. While primary consumers are always herbivores; organisms that only feed on autotrophic plants, secondary consumers can be carnivores or omnivores. Tertiary Consumer Definition A food chain contains several trophic levels. These animals are often called predators because they hunt down and kill the food they eat. Consumers are found in food chains, where they are joined by two other groups – producers and decomposers.

High-level consumers get even lower amounts of energy. Acquired when secondary consumers eat producers C. Lost as trophic levels increase D. Only gained through hunting prey, 3. This energy loss also implies that higher-level consumers must eat more food. Secondary Consumer. Long ago, even humans were considered secondary consumers because other mammals could easily hunt them. Consequently, in a given ecosystem there are generally more producers than 1st-level consumers, and more 1st-level consumers than 2nd-level consumers, and so on.
