Answer:
B. The majority of nitrogen flows through ecosystems, and relatively little recycling occurs.
Explanation:
Nitrogen cycle are the different ways in which nitrogen is converted into multiple chemical forms as it circulates around atmosphere, terrestrial and marine ecosystems. Nitrogen can be added to the biosphere through volcanic activity and the weathering of volcanic rocks.
The application of chemical fertilizers to agricultural fields leads to large outflows of nitrates to groundwater and streams.
Soil pH has a large impact on the rates of nitrogen fixation and nitrification.
Small amounts of nitrogen are lost into sedimentary rocks and sediments of the deep ocean.
Answer:
D. Soil pH has a large impact on the rates of nitrogen fixation and nitrification.
Explanation:
The nitrogen cycle describes how nitrogen moves between plants, animals, bacteria, the atmosphere (the air), and soil in the ground. Nitrogen is an important element to all life on Earth. Different Nitrogen States. For Nitrogen to be used by different life forms on Earth, it must change into different states.
