What is the total number of trophic levels in the food web grassgrasshopperfrogowlsnakerabbitfoxaspen?

In the food web consisting of grass, grasshopper, frog, owl, snake, rabbit, fox, and aspen, there are typically four trophic levels. The first level includes primary producers (grass and aspen), the second level consists of primary consumers (grasshoppers and rabbits), the third level includes secondary consumers (frogs, snakes, and owls), and the fourth level contains tertiary consumers (foxes). Thus, the total count of distinct trophic levels is four.
