Answer:
An ecliptic is the trajectory drawn by the race of the Sun on the celestial vault. This is the geocentric point of view, seen from the Earth.
An eclipse occurs when the Moon passes through this plane (in two points, called nodes), precisely at the time of the New Moon or Full Moon. The Sun, the Earth and our satellite are then aligned. In the first case, it will be a solar eclipse (the Moon is between the Earth and the Sun). In the second, it will be a lunar eclipse
