Which process plays an important role in the cycling of both carbon and nitrogen? a. photosynthesis b. transpiration c. decomposition d. respiration

The right answer is C. Decomposition

The decomposition of organic matter is the result of a series of chemical reactions that result in the transformation of complex organic compounds into simple inorganic compounds. The mineralization of organic matter is a fundamental process because it results in its transformation into simple elements, the only ones that can be assimilated by plants.

In fact, the decomposing microorganisms need nitrogen to degrade the carbon: when the residues to be decomposed have a C / N ratio (ratio between the total amount of carbon and the total amount of nitrogen), the microorganisms do not take up carbon. nitrogen in the medium. On the other hand, when a large quantity of high C / N residues is buried, they take up nitrogen in the soil for their own metabolism, which, under certain conditions, may compete with the plant population grown for nitrogen (" nitrogen hunger ").

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
