If the biomass that can be supported in higher trophic levels is dependent on the number of primary producers, then the diversity should increase as latitude decreases.

Question

As latitude decreases (moving towards the equator), there is more available sunlight and warmer temperatures which favor increased primary productivity. This increase in primary productivity can support a greater biomass of herbivores and therefore a higher trophic level diversity.
