Which of the following statements is not true?

The detritivores are the organisms which feDetritivores feed at all trophic levels including the producer level. Detritivores primarily consume detritus (dead organic matter) that not only includes animal detritus but also plant detritus, such as fallen leaves, broken off twigs, and stems of dead plants.
(1) Omnivores and can consume food from multiple trophic levels. 
(3) Primary consumers are the organisms that directly feed on primary producers (plants). They are typically herbivores, consuming plant material as their primary food source.
(4) At each trophic level, some energy is lost as heat, and only a portion of the energy is transferred to the next level. As a result, the energy available at higher trophic levels is lower than at lower trophic levels, causing the energy pyramid to diminish or decrease in size as we move up the pyramid.ed on the dead organisms which belong to all the trophic levels.
