Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.
Answer:
In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.
Explanation:
- An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.
- The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.
