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.

Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.
Hope this helped! :)
There are many ways humans can reduce the amount of endangered and extinct species. However, I would say by reducing pollution and logging/mining. Nearly 318 species have become extinct due to pollution. The reduction of carbon emissions would be a good way to curb the amount of pollution produced by humans.
