Humus creates good soil tilth, which is an indirect benefit of microorganism action.

The correct answer will be-true.

Explanation:

Humus is the dark matter of the soil composed of the dead organisms and the micro-organisms which increases the organic matter of the soil.

The soil tilth is the physical property of the soil which is helpful for seedling emergence and root penetration due to large pore spaces for water movement and air filtration.

Since humus acts as a source of nutrients to plants as well it increases the porosity of the soil which indirectly improves the tilth of the soil therefore true is the correct answer.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

preservation because he preserves part of the land and preserves means save
