How many trophic levels are there typically in a community

Trophic levels make up the food chain. All food chains and webs have at least two or three trophic levels. Normally,  the maximum trophic levels are four.  

The levels are:

1:  Plants and algae (producers).

2: Herbivores (primary consumers).

3: Carnivores (secondary consumers).

4: Carnivores that eat other carnivores (tertiary consumers).

However, many consumers also feed at more than one trophic level.
