Answer:
B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.
Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.
Answer:
Deforestation is one major human activity that harms both people and organisms. Cutting down trees lowers Earths ability to create fresh air, which leads to more toxic and polluted areas that can cause problems with breathing and even lead to lung cancer. Deforestation can harm other organisms because many animals such as birds, squirrels, and owls, look to the trees for a habitat. However, as we destroy they can cause a decrease in population which leads to an even bigger problem in the food chain.
