Answer: Africa includes the rich source of water drainage in the form of rivers.
Explanation:
The course travelled by the major rivers in Africa are as follows:
1. Congo: Center to north and further to the Western region finally drains into the Atlantic Ocean.
2. Nile: Northeastern part to the North and then finally to the Mediterranean Sea.
3. Zambezi: South eastern to Indian Ocean.
4. Niger: West to the Guinea Gulf.
I'm assuming you meant subsistence farming? If so then yes, it would be a large problem because they would then not have enough food to feed themselves.
Answer:
To calculate the RNI, demographers subtract the death rate (number of deaths per 1,000 people/year) from the birth rate (number of birth per 1,000 people/year) and convert the answer to a percentage.
Equation for Rate of Natural Increase (RNI):
(BirthRate/1,000) – (DeathRate/1000) = (BR-DR)/1000 = RNI %

Hydrogen is used by plants which combine it with carbon during the photosynthesis process and release oxygen into the atmosphere which is used by all living beings.
