u would need water, food, air, other people, and last of all, everything we have on earth!
All animals need water, that is why it is so hard to find life on other planets. However some bacteria on the other hand do no need water to survive.
We only can live on Earth because Earth provides us with everything we need. Other planets such as Mercury or Jupiter cannot hold us. For example, Mercury or the other planets don't have water, or fertilized areas to plant vegetables and plants. Jupiter and the other gas giants such as Saturn and Neptune don't have a surface, so we would probably die. The most and final important thing is that the other planets don't have air.
probably around the same things we would need to survive oxygen or water food or some other source of energy gains as constantly as needed
=we need planets because if we didn't we couldn't travel the world and no one will be able to go on holiday! But if you would travel the world were would you go if you had no planets=
Blubber fur and some other stuff
I think they would breathe with carbon dioxide and would live on mars.
You will need the same things to survive as you need in any other situation: food and water. Shelter is already provided by the cave. Fire would be helpful, for offering warmth and a means for cooking one's food.
they need it to survive
Yes, bees need oxygen to survive. Just like other living organisms, bees require oxygen for respiration to produce energy and carry out their bodily functions. Without oxygen, bees would not be able to survive.
They need to survive because they control aphid population and some other small bugs.
because you need biological life. You also need liquid water. Mars does have oxygen @ very low levels. Other planets do have oxygen.
You need rockets so you can travel to space and visit other planets. Without rockets we would know nothing about astronomy.
