Explanation:

According to Jean Baptiste Lamarck, fossils are the direct evidence of evolution and nucleotide sequence is the direct evidence of molecular evolution

He also explained about the use and disuse of organs, the organs which are used in priority will develop and the organs which are not used by priority will disintegrate

Lamarck said that vestigial organs in different organs is the direct evidence of use and disuse of organs  

answer; i believe the answer is (polygenic inheritance;

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.
