It is not. Mars is a planet, a mass of rock and minerals.
So far, we have detected no certain evidence that there are any living things on Mars, although our half-dozen or so landers could easily have missed some unusual or strange form of life. And it's possible that there once WAS life on Mars, but that it has died off long since.
Pluto was re-classified as a dwarf planet in 2006 by the International Astronomical Union (IAU). A new definition for a planet was established, Pluto did not fit the new criteria, so was deemed a dwarf planet. Like Earth and the other planets, it is known to be spherical in shape and is in direct orbit the, but unlike the Earth and other planets, it does not `dominate` its orbit. That is to say that there are a high number of other bodies at the same orbital distance.
This question makes no sense at all - please read your assignment again and copy the question correctly to get an answer.
It has human life, all three forms of water (ice,liquid, snow), it has an atmosphere that protects us from the worst of the sun, and it is the perfect distance away from the sun to maintain life (habital zone).
Pollution makes the Earth angry. At least, in a metaphorical sense.
water, air, soil and rocks, living things
There is currently no known planet that is habitable for all living things. Different organisms have different environmental requirements, which makes it challenging to find a single planet that can support the diverse range of life found on Earth.
Oxygen makes up about 21% of Earth's atmosphere. It is also found in various forms in water, rocks, and living organisms on the planet.

Earth is the only planet known to support life.
Planet Earth - about 80%.
A planet cannot be considered "living" as it is a non-living celestial body. However, the presence of certain conditions such as liquid water, a stable atmosphere, and organic molecules can make a planet potentially habitable for living organisms.

Water, atmosphere.
The Earth's core makes up about 15 of the planet's total volume.
