Trophic Level
The lion is one of the apex predators in the savannah food web or food chain, often hunting other animals smaller than the lion in the act of predation in the biosphere. When the lion dies, the scavengers decompose the body and return it to the soil for the primary producer to prosper. This is an illustration of the trophic level of the savannah.

What Are Trophic Levels
Trophic levels are a structure that researchers use to organism all the organisms in a single area or biome based on the predator and prey relationship with the other organisms in the area. The structure of the trophic level will often be in the shape or form of a pyramid as the higher the trophic level the lower the number of organisms in said level.
How to Categorize Organisms Based on Trophic Level
The trophic level of an organism will easily allow the researcher or scientist to comprehensively know the relationship between the organism and the other organisms in the habitat or biome. If you want to learn more about trophic levels and their structure, you can read any of the articles above. (Good reads include Trophic Level Index, Review Lake Trophic Level Index, and Trophic Level Troubles)
1.) Pick a Specific Habitat or Biome
Begin by picking a specific habitat or biome you would like to categorize all the organisms. This will dictate the number of organisms you will have to organize based on their trophic level. This will provide a structure that will provide you with the necessary context and theme you can use in the whole illustration.
2.) Research All the Organisms In the Chosen Habitat or Biome
When you have finished choosing the habitat or biome, you will now research all the organisms in the given area. This should include the various plant life, bacteria, insects, viruses, and animals living in the habitat or biome.
3.) Research and List Out the Organism’s Food Production and Food Source
After the previous step, you must select an organism and research its food production and source. This will help you easily assign the organism to its appropriate trophic level.
4.) Based on the Food Source, Place the Organism on the Associated Trophic Level
Based on the food source of the organism, one can easily assign the organism to the correct trophic level. If the organism produces its food via sunlight, then it should be at the primary producer’s level. But if the producer has a predator, then it should be categorized accordingly in the consumers part of the trophic level.
5.) Repeat Steps 3 and 4, Until You Have Finished Categorizing All the Organisms in Their Appropriate Trophic Level
After finishing steps 3 and 4, you must now repeat said steps until you have finished categorizing all the organisms to their appropriate trophic level. You can also arrange the organisms in a pyramid-like structure.
FAQs
The five trophic levels function as categories of specific organisms that the researcher or scientist will place and add to the food chain or food web. The first and the lowest level in the trophic level is called the primary producers. These organisms often manifest as the plant life in a given biome, as they absorb nutrients from the ground and chemical energy from the sun. The second level above the primary producers is the primary consumers. The final level called the apex predator is the organism at the top of the food chain or food web that has no consumers above them in a given ecosystem. These organisms will only be reintroduced to the energy cycle through the decomposition reaction of their dead bodies via the decomposers.What are the functions of the trophic level?
The trophic structure is a pyramid-like structure that organizes the organisms in different trophic levels and biomass based on their various relationships like predator-prey, parasitism, mutualism, and commensalism. This also indicates the relationship the various organisms will have with the other organisms below their trophic level. An example of this relationship is the presence of a secondary consumer benefiting the primary producers as it reduces the total amount of organisms preying on them.What is a trophic structure?
The 10% rule is a rule that governs how much potential energy is being transferred and absorbed via consumption and chemical reactions in the body. This rule states that the energy transferred between trophic levels is only capped at 10%. Primary producers produce 100% potential energy, which is reduced to 10% when the primary consumers eat the primary producer for energy. This is true between the primary, secondary, tertiary consumers, and the apex predator reaching 0.01% Energy gained by the apex predator.What is the 10% rule?
The trophic level is a position an organism occupies inside a specific food web or food chain in a given ecosystem, biosphere, or biome. Being able to classify and categorize organisms on their correct trophic levels will easily allow you to create a comprehensive food chain and food web.
