No. day and night are the product of the planet's rotation only,
regardless of where it is in its orbit, or how far from the sun.
To be precise, there is a very small effect. The elliptical orbit causes slight variations in the position of the Sun in the sky.
Our 24 hour day is called the "solar day". It's based on the position of the Sun in our sky.
24 hours is the average (or mean) day length.
It's called the "mean solar day".
The earth orbits around the sun in an elliptical path. It is too oblong to be considered circular orbit.
They are orbits and they are elliptical in shape. So the answer could be "orbits" or it could be "ellipses".
Earth travels in a slightly elliptical path around the Sun.
Planets orbit the sun because gravity keeps them from escaping, and momentum keeps them moving forward. The orbits are elliptical, which is like an oval.
According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre.

The shape of the earth's orbit is elliptical, not circular.
It's an elliptical orbit. it is also an mutha
No. A circle is an unstable shape for an object orbiting another. An orbit is between slightly and very elliptical (egg-shaped). If an object is placed in a circular orbit, the orbit will quickly deteriorate to an elliptical orbit. Added: Mar's elliptical eccentricity is rather above average for a planetary orbit. Not quite as large as Mercury, but large enough.
Your question is unclear, but... ...the SHAPE of an orbit is called an ellipse or elliptical.
