Question

Are the food web levels, producer, primary consumer, secondary consumer? A source would be nice too.?

Answer 1

Yes and don't forget tertiary consumers and decomposers.  

An example of a food chain within a food web would be:

producer - grass

primary consumer - grasshopper (herbivore)

secondary consumer - small bird (omnivore)

tertiary consumer - large bird (hawk) (carnivore)

decomposer - fungus such as mushroom;  bacteria are also powerful decomposers
