It comes from the food that we eat.
Protein
RE:I'm not competely sure, but I think its sunlight. It is because: carbon dioxide + water (+light energy) ---> glucose + oxygen
Blood
when you breathe in, you breathe in oxygen which is then transported to your cells and they use it to and food to respirate.
The energy comes from the sun!
The energy photosynthesis comes from the sun's light energy.
I'm going to go out on a limb here and say food.
It comes from the food you eat or the water you drink. You can't live without food, and if you try, you will be very weak. That's why food gives us energy.
They don't. Dolphins have lungs, and have to Surface to Breathe. Thye hold their breath while diving.
Breathe in. Breathe out. Know that we are all fractures of the same energy source, be it God, Allah, or Lupercus. Know that you see all around you and experience it. Know that you can change and bend these experiences depending on mood and intent. Breathe in. Breathe out. Breathe in, And out. You are now everything, and everything is you. you come from the same source, and are merely different energy patterns of the same energy. Breathe in Breathe out. According to Deepak Chopra anyway.
Yes manatees are mammals which means they breathe air
i think it's Ocean waves
Because there's nothing out there to breathe.
i think its from the energy stored by plants that lived hundreds of millions of years ago.=]
from the blood stream, both carbohydrates and oxygen.
they come out there mom
whales can breathe underwater that is why they live in water but sometimes they have to come up to breathe like fish
For human life you need Oxygen (whta we breathe), water as our bodies contain 61% of it, and energy, the energy wil somehow come from the sun. there may be others but i dont know xD
