The grasses occupy the lowest trophic level (base) be- cause of their abundance. • The next higher trophic level is primary consumer - herbivore (example – grasshopper). • The individual number of grasshopper is less than that of grass. The next energy level is primary carnivore (example – rat). • The number of rats are less than grasshopper, because, they feed on grasshopper. The next higher trophic level is secondary carnivore (example – snakes). They feed on rats. • The next higher trophic level is the top carnivore. (Ex. Hawk). • With each higher trophic level, the number of individual decreases.
