Because there is such a large amount of available energy, the secondary consumers (fish etc.) The secondary consumers in these food chains are the cheetah hyena and the lion. For example, if a population of foxes becomes too large it could put pressure on rabbit populations. 487 lessons. The African savanna is located in the middle and Southern regions of Africa.
