The correct option is B Biomes of Africa
Biomes are a collection of ecosystems that have a similar topography, climatic conditions, temperature, precipitation and similar types of species. In the image, we can observe large masses of land that come under the forest biome (tropical rainforest), the grasslands and even deserts. Each of these biomes can house thousands of individual ecosystems. Ecosystem biodiversity on the other hand, would denote the sum total of the biodiversity that exists within a specific ecosystem and not in a biome. The aggregation of biodiversity in various similar ecosystems makes up a biome.
