Organic matter with a ratio results in a low net release of nutrients during decomposition. this is because microbial growth is more limited by than it is by low c: n; energy; n supply high c: n; n supply; energy high c: h2o; water supply; energy low c: h2o; energy; water supply low n: h2o; n supply; water supply

high C:N; N supply; energy

Explanation:

Nitrogen supply is required for microbial growth to synthesize nutrients such as amino acids and proteins. For a high C:N ratio, the amount of nitrogen supply is considerably small compared with the amount of carbon. As a result, a low amount of nutrients is released during decomposition.

In the given question, the organic matter with a __high C:N___ ratio results in a low net release of nutrients during decomposition. This is because microbial growth is more limited by __N supply than it is by __energy.
