Answer:
To give the planet Mars the ability to support life like life on Earth, we would have to find a way to change the planet’s
<u>Atmosphere and raise its temperature</u>
<u></u>
Explanation:
Thing common in living- organisms: grow , take energy, get rid of waste,evolve in response to environment
First we need to know why Earth is suitable for life :
1. Its atmosphere : which helps in maintaining suitable environment for living.The atmosphere on Earth maintain its temperature.
It contains Gases like : Carbon dioxide , Nitrogen ,Oxygen.
These gases are required by the different living things for survival .
2. Sources of energy : Every living organism need source of energy for their growth. Even a microscopic organism require food to carry out its life- process.
Water , Sunlight , gases are some important food sources for living things.
<u>Why Life do not exist in Mars?</u>
In 1986 scientist mistakenly thought that there is life on mars also. But no solid proof was found anywhere.
- There is Only CO2 gas present in Mars.But this is not enough for life. Othere gases should also be their( Human being need O2 gas for breathing)
- The temperature on Mars can go very low(-60 degree celcius).It can be lower than -60 in winter season.
<u>So to support life on Mars , Raise its temperature and Atmosphere needs to be changed</u>
