Tropical Grassland or Savanna 

These are hot, tropical areas, averaging 24–29ºC with a low or seasonal rainfall of between 70 and 130 cm per year.

As with grasslands, the predominant mammals are the grazers. 

 In Africa, the large herds of grazing animals provide food for many different kinds of large carnivores (lions, hyenas, leopards). 

The world’s greatest assemblages of large mammals occur in the savanna biome.

T1 cells are mIgMhi, mIgD -/lo, CD21-, CD23-, CD24+, and CD93+. 

T2 cells differ from T1 cells in having higher levels of mIgD and in expressing CD21 and CD23.
