Answer: Only some of the organisms survive and reproduce.
Natural selection is a process of differential survival and reproduction in which organisms bearing favorable phenotypic traits survive in changing environmental conditions. Therefore, only some of the organisms survive and reproduce which have suitable phenotypic trait. For example a population of beetle bearing two colors red and green. The green colored beetles mimic the color of grass will remain undetected by birds and those with red color easily observed and detected by birds. Hence, only green beetles are favored for survival over red beetles.

Answer:
Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.
Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.
