I saw in a book a food chain which was grass --> grasshopper --> frogs --> snake --> hawk this food chain contains 5 trophic levels but a food chain consists of 3-4 trophic levels.how is this possible?

It is because due to ten percent rule: only ten percent of the energy in any trophic level is available for the next trophic level. The higher you feed in the food chain the less energy is available.
