Air Resources — Quiz

Question 6 • Earth and Space Science

A dry, compacted field with little vegetation has reduced microbial activity. What is the likely result for air-related resource cycling?

Answer
A
increased production of oxygen by roots
B
increased nitrogen conversion and stable gas flow
C
decreased gas cycling and less support for plant growth
D
faster carbon absorption due to exposed soil

Explanation

Microbes and plant roots help cycle gases and nutrients in soil, while soil pores allow air to move. Dry, compacted soil with little vegetation has less microbial activity and poorer air movement, so gas cycling decreases and plants receive less support for growth. Exposed soil does not make carbon absorption faster.
