Some of them eat seeds and insects. Another biome is the rainforest. People live there in huts, and it's hot there all the time. Even though it rains, it doesn't get cool there. It stays hot, kind of like the desert.
Tropical rainforests are around the west coast of Africa.
There are tons of animals in the rainforest. The last biome is savannahs. There are savannahs in the Great Rift Valley. Also, there is the largest volcano there, and it is called Mt. Kilimanjaro. There is also a savannah called the Serengeti Plain, and in the Serengeti Plain there are animals like lions and hyenas.
