Model answer

(a) Forest belt: mangrove swamp, freshwater swamp, rain forest; savanna belt: Guinea, Sudan, Sahel savanna; shown in correct bands from south to north.
(b) e.g. Rain forest: heavy rain all year and high temperature give tall evergreen trees; continuous growth gives dense layered forest; high humidity supports lianas and epiphytes; heavy rain causes leaching. (Or Sudan savanna: long dry season gives short grasses and scattered drought-resistant trees, deciduous trees, long roots.)
(c) Rain forest: cocoa, oil palm, rubber, kola, yam; Guinea savanna: yam, maize, guinea corn, rice, benniseed; Sudan savanna: groundnuts, cotton, millet, sorghum.

Explanation

Two broad belts are forest and savanna.
