Most ecosystems can be visualized as a pyramid with many organisms in the lowest trophic levels and only a few individuals at the top. Give an example of an inverted numbers pyramid (use Internet for examples).
An example of this can be the grasslands that occupy the lowest tropic levels at the base due to their abundance.
The next higher levels are the primary consumer as grasshopper that feeds on them are small in numbers and thus is said to be an inverted or opposite ecosystem pyramid.
