The feeding positions in a food chain or web are called trophic levels. The different trophic levels are defined in the Table below. Examples are also given in the table. All food chains and webs have at least two or three trophic levels. Generally, there are a maximum of four trophic levels.
Trophic Level
Where It Gets Food
Example
1st Trophic Level: Producer
Makes its own food
Plants make food
2nd Trophic Level: Primary Consumer
Consumes producers
Mice eat plant seeds
3rd Trophic Level: Secondary Consumer
Consumes primary consumers
Snakes eat mice
4th Trophic Level: Tertiary Consumer
Consumes secondary consumers
Hawks eat snakes
Many consumers feed at more than one trophic level. Humans, for example, are primary consumers when they eat plants such as vegetables. They are secondary consumers when they eat cows. They are tertiary consumers when they eat salmon.

The division of organisms on the feeding level is known as trophic level. This can be represented in the ecological pyramid.
