In a trophic pyramid, decomposers are not always included in the linear sequence, as traditional food chains mostly focus on the movement of energy among producers and consumers. They can be considered as operating at all trophic levels. Some ecological models place them at the bottom of the py...
Definition noun, plural: primary consumers Anyorganismthat consumes or feeds on autotrophs Supplement Afood chainis defined as a feeding hierarchy in which organisms in an ecosystem are grouped into trophic (nutritional) levels and are shown in a succession to represent the flow of food energy an...

Primary production provides for all trophic members as it provides energy to primary consumers that in turn provide energy to secondary consumers and so forth. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. ...
Primary consumers make up the second trophic level as they feed on primary producers. In other words, primary consumers are organisms that take up food directly from plants.

The primary consumers in turn become the food for secondary consumers which prey upon them. Tertiary consumers subsequently feed on secondary consumers. While this path may seem quite linear, many organisms fulfill different roles at different stages of their life. For example, many large fish begin...
In biology, net primary productivity is defined as the difference of the energy that’s fixed by the autotrophs and their own respiration losses. It is the net primary productivity that provides the channel for secondary productivity. For all the activities of consumers and heterotrophs, it’s ...
A key question in microbial ecology is what the driving forces behind the persistence of large biodiversity in natural environments are. We studied a microbial community with more than 100 different types of species which evolved in a 15-years old biorea
