Answer:
A- soil bacteria converts usable nitrogen into nitrogen gas
Answer: The correct option is B. 25% of the area is vegetation and 75% is roofed or paved.
Vegetation can cause precipitation and reduce runoff. Leaves and stems are used in capturing rain and prevents the rainwater to reach the ground. Dense vegetation with higher surface area under vegetation absorbs water and prevents runoff. Pavements or roofs cause the runoff water by filling the waterways as there is no vegetation for water absorption which leads to overfilled waterways and in turn cause flooding.

Potential Explosions
Radiation
Radioactive Waste

Nuclear Fission is not a good source of energy. This is by reason of only 0.7% of the uranium being captured. This is small even if one doesn't mention that only 40% of that 0.7% is converted into usable energy. There are also chances that the power plant could explode during conversion. All of this evidence points to the fact that Nuclear Fission and Nuclear Energy themselves should not be relied on.

Sun and Stars
7)
Uranium and Plutonium
Photosynthetic organisms capture energy from sunlight with pigments.
