Hummus is an important component of healthy soil. how does hummus form?
denis23 [38]

Answer:

Humus (hummus) is a dark organic matter in the soil which is produced by the decay of leaves or twigs (leaf litter). The litter is decayed in the soil by the action of microbial communities and chemcial reactions (together called as biogeochemical reactions). This process is also known as decomposition. The higher humus content in the soil makes it more fertile because there are more nutrients releasing due to increased turnover of the decomposing bacteria. Further, humus formation is increased if more water (moisture content) and oxygen is available.

Option-3 and 4

Explanation:

In the given question, the table of the different nitrogen bases of a different organism has been provided in which the number of bases has been mentioned.

In the table, the amount of thymine is almost similar or equal to the adenine while the number of guanines almost equal to the cytosine for a particular species. This data follows the Chargaff postulates which state that adenine bind thymine and cytosine bind guanine therefore the number of complementary bases will be equal.

Thus, Option-3 and 4 are correct.
