It is true. Earth moving around the Sun, WITHOUT any other objects in the Universe, and WITHOUT considering General Relativity, would be an unchanging ellipse. However:* As a result of the warping of space-time (General Relativity), the periapsis will change over time. That is, the ellipse, while maintaining its shape, will change its position in space.
* Other objects, mainly in the Solar System, pull on the Sun and on the Earth. This will actually change the shape of the orbit over time.
The effect, in both cases, is very small, at least in the short term.
No, the sun is located at one of the two foci of Earth's elliptical orbit, not in the exact center.
Earth's orbit around the sun is fairly typical compared to other planets in our solar system. It follows an elliptical path, with the sun at one of the foci. The shape and orientation of Earth's orbit contribute to the changing seasons and variations in solar intensity.
As an elliptical orbit is any orbit that isn't perfectly circular, everything has an elliptical orbit. The planets Mercury and Pluto have the most elliptical orbits of the planets, and are easily seen to be oval shaped. Comets also have highly elliptical orbits.
Yes, earth's orbit is slightly elliptical. Venus's orbit varies only slightly from a perfect circle, while dwarf planet Pluto has the most highly eccentric orbit. In general, all planets orbit around the Sun in an elliptical orbit. This was first discovered by Johannes Kepler and was described by his three laws of planetary motion.
A revolution: The Earth revolves in an elliptical (oval) orbit around the Sun. This orbit is planetary; the Sun is a star, and a large object that orbits a star is known as a planet.

The earths orbit around the sun is almost circular.
Not much would change. Note that the seasons are NOT related to changes in the distance from the Sun.

No, the sun is located at one of the two foci of Earth's elliptical orbit, not in the exact center.
Earth's eccentricity Eccentricity is defined as the difference in shape between an ellipse and a perfect circle. In a similar fashion to Earth's obliquity, the more uniform Earth's orbit is (more like a perfect circle), the less difference there is in climate change throughout the year.
Because it is pulled in by the earths gravity and therefore orbits the earth.
The periodic change in the shape of Earth's orbit, known as Milankovitch cycles, can impact Earth's climate by affecting the amount and distribution of solar radiation reaching the planet. These cycles influence the timing and intensity of the seasons, which in turn can lead to shifts in temperature and ice sheet formation. Over long periods of time, these changes can contribute to the onset of ice ages or interglacial periods.
Yes. They orbit the Sun and as per Kepler's first law they follow an elliptical path. Do note that a circular orbit is a special type of elliptical orbit.
The motion of the Moon would change from an elliptical orbit to a straight line.
