An example of an endothermic process is Boiling.
An endothermic reaction is any chemical reaction that absorbs heat from its environment. Boiling is a course by which a liquid changes into a vapor when it is heated to its boiling point. The shift from a liquid phase to a gaseous phase happens when the vapor pressure of the liquid is of the same level to the atmospheric pressure exerted on the liquid.
Pollination cycles do not really have any direct effect with the soil. Releasing moisture from leaves does replenish some water needed in the soil that is cycled back through the transport systems of plants but does not hold back soil. Photosynthetic activities only draw up nutrients, minerals, and water from the soil through roots.
Therefore, the often elaborate ROOT SYSTEMS are the answer. This is because the roots hold the plants in the ground (soil) and by this, the plants prevent natural disasters, artificial actions, and/or excess water to wash away soil. The roots help to reinforce the soil and hold it together.
