Answer:
Soil
Explanation:
Plants get their nitrogen from the soil. Although nitrogen is present in the air the structure of the molecule is strong and so would require large amounts of energy from the plant to break down.
The breaking down of nitrogen is a process called nitrogen fixation. Bacteria and archaea in the soil convert nitrogen into ammonia; breaking down the tough triple bond of nitrogen to be more readily absorbed by the plant.

Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
