Plants, algae, and bacteria occupy the first trophic level of an organism.
poneer species
Humans belong to the third trophic level. Humans belong to the third trophic level if they are omnivorous, however there are many humans who are vegetarian or even vegan, and these humans would be considered second trophic level consumers. This is because they only eat producers (flora).
Organisms within an ecosystem are classified into trophic levels to show their role within that ecosytem and also to show the energy flow from one type of organism to another. A trophic level contains 4 sub-levels. In the first level are producing organisms which convert the radiant energy from the sun into chemical energy. The second level is occupied by primary consumers (usually herbivores) which consume the producers in order to obtain the chemical energy they need to survive and to build up organic matter. Secondary consumers come after, in trophic level three, and consume the primary consumers. The last level contains Tertiary consumers which consume the primary consumers and/or the secondary consumers within the ecosystem. This interdependence among life forms is often called the food web, or in the case of soil, the soil food webTry making your answer shorterWell i know its either mountain lion, maple leaf or moose
Primary producers-- these are the plants and other producers that create their own energy via sunlight or other means. Consumers ingest these plants, placing them at the second level of a trophic pyramid.

An ecological pyramid is simply a graphical representation of the relationship at each trophic level in a particular ecosystem. There are three types of ecological pyramids: of numbers, of energy, and of biomass. For example the pyramid of numbers is a representation of the number of organisms in each trophic level, with herbivores at the bottom as primary consumers, followed by first level carnivores and so on.

1st level consumers are any heterotrophs (animals that do not harvest food through photosynthesis or chemosynthesis) that eat producers (plants, bacteria, things that make their own food). 2nd level consumers are carnivores or omnivores that eat 1st level consumers, and the 3rd eats 2nd, and so on and so forth. Well a 3rd level consumer is a decomposer second is a carnivore first is a herbivore
