Answer Details
The correct sequence of biomes from northern to southern Nigeria is: Sahel savanna → Sudan savanna → Guinea savanna → tropical rainforest → estuarine.
The northern part of Nigeria is mostly made up of the Sahel and Sudan savannas, characterized by grasslands and scattered trees. Moving further south, we encounter the Guinea savanna, which has denser vegetation, including trees, shrubs, and grasses. The Guinea savanna gradually gives way to the tropical rainforest, which has high rainfall and is home to a diverse range of plant and animal species. Finally, the southernmost part of Nigeria is the estuarine biome, which is characterized by wetlands, marshes, and swamps, and is influenced by tidal activity.
So, the correct sequence of biomes from northern to southern Nigeria is determined by the gradual transition from the drier savannas to the wetter rainforest and estuarine biomes as we move southward.
