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.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
