Final answer:
The fall of Ghana was influenced by its participation in the slave trade, the Almoravid invasion, and the collapse of the trans-Saharan trade route.
Step-by-step explanation:
The fall of Ghana can be attributed to multiple factors. One of the main reasons was its participation in the slave trade, which brought Ghana into competition with neighboring countries that eventually conquered it. Additionally, the Almoravid invasion weakened Ghana, leading to its eventual collapse centuries later. Lastly, the collapse of the trans-Saharan trade route meant that Ghana was cut off from its main source of income.
