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...
As you now know, predators are higher in the food chain than their prey. Most predators are considered to be secondary and/or tertiary consumers, although primary consumers that eat plants could be considered predators under the definition of herbivory. Prey almost always outnumbers predators, whic...
Definition noun, plural: tertiary consumers Anyorganismthat consumes or feeds largely on primary and secondary consumers Supplement Anecological pyramidis a representation in the shape of a pyramid to show the feeding relationship of groups of organisms, and the flow of energy or biomass through the ...

What are Producers and Consumers in Biology? – Definition & Examples Biodiversity: Definition, Levels and Types of Conservation Methods Phosphorus Cycle: Definition, Steps and Interesting Facts
In a lake, certain ecological constraints such as the primary producers (plants, algae) play a feeding function in relation to other biotic components, such as consumers (e.g., fish). In turn, fish, as constraints acting in an organisational closure with plants, play an egestion function ...

Primary consumers that feed on detritus include fungi, bacteria, protozoans, and other creatures. Figure 4: A grazing Food chain. Image Credit:PMF IAS. Examples of Organisms and Food Chains Single-celled organisms known as phytoplankton supply food for small shrimp known as krill in one marine ...
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 ...
