What is the major source of secondary aerosol formation in Africa?

The major sources of secondary aerosol formation in Africa are biomass burning, windblown dust, and sea-salt emissions. Biomass burning, or open burning of organic materials, is a common human activity in Africa due to its traditional methods of land clearing, cooking, and even means of warfare and is the source of much of the aerosol formation in the region. Windblown dust is especially prevalent in the arid and semi-arid regions of Africa, where the soil is not protected by vegetation, and is a major source of aerosols. Sea-salt aerosols form when sea spray is driven into the atmosphere by wind and create aerosols, particularly in coastal regions.

How does nitrogen fixation occur in legumes?
Nitrogen fixation in legumes occurs when the root nodules of the plant form a symbiotic relationship with bacteria of the genus Rhizobium. The bacteria are hosted by the plant, and they use the oxygen in the air to convert atmospheric nitrogen into ammonium ions. The plant then transfers these ions to the root nodules, where they are used to synthesize proteins and other molecules.
