Which of the following statements about the nitrogen cycle is FALSE?
A. Nitrogen can be added to the biosphere through volcanic activity and the weathering of volcanic rocks.
B. The majority of nitrogen flows through ecosystems, and relatively little recycling occurs.
C. The application of chemical fertilizers to agricultural fields leads to large outflows of nitrates to groundwater and streams.
D. Soil pH has a large impact on the rates of nitrogen fixation and nitrification.
E. Small amounts of nitrogen are lost into sedimentary rocks and sediments of the deep ocean.

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.

b) chemical ( the chemical breakdown of food is accomplished by enzymes. )
