One prey-predator relationship in the reef is the eel-shrimp
relationship. The eel predates on shrimps, crabs and small fishes. The eel
hides and awaits its prey in the crevices
of the coral reefs. They only emerge from the crevices in the night to hunt
shrimps and other prey.
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.
