Gravity.
The objects interacting in this case are the fruit and the Earth. The force that causes the fruit to fall to the ground is gravity, which is the attraction between the mass of the fruit and the mass of the Earth.
Gravity is the force responsible for the downward motion of falling fruits. When a fruit is released or detached from a tree, gravity pulls it towards the ground, causing it to fall.
Ethylene

because gravity is constantly fighting against the fruit until the fruit gives up and falls to the ground.
That they both form from buds is how flowers relate to fruits. In the case of flowering and fruiting plants, the flower prepares the way for the fruit. The sequence is the formation of the flower by the bud. Then the fading of the flowerleads into the formation of the fruit. The seeds of the fruit fall to the ground. The budding to flowering to fruiting cycle begins anew with the growing of each fruit seed into the mature flowering and fruiting plant.
auxins are group of related chemical substances which activity greatly affect the physiological processses in plant and animal.auxins helps in stimulating plant growth and also hasten fruit ripening.
Ethylene is the plant hormone used by the industry to cause fruit to drop from a tree. Ethylene is commonly used to trigger fruit ripening and promote the shedding of older fruits to allow for new growth.
The carapa plant disperses its seeds through gravity. The tree produces fruits containing seeds that fall to the ground when ripe. Some seeds may also be dispersed by animals that eat the fruit and later excrete the seeds away from the parent plant.
They jump and land on a plant and touch the ground and fall of the plant.

Ocotillo plants reproduce through seeds that develop in the fruit produced by the plant's red tubular flowers. The plant can also reproduce through rooting of stem segments that fall to the ground. Ocotillo seeds require a period of cold stratification before germination can occur.
