many things. one, energy source. For humans, that's food and oxygen. Oxygen is used in aerobic respiration, which produces about 32 ATP (which is energy that our body can use). Food contains nutrients and sugars that help produce energy. ATP can be used to restart the cycle, and break down food to yield more ATP/energy. As for something like plants, they use photosynthesis. This uses the Sun's light as energy to "kick-start" the energy process. they use Anerobic (as suppose to human's aerobic) respiration. this yield about 8 ATP (which as you can see, is less than the 32 ATP aerobic respiration yeilds). They then use that ATP to carry out all of it's functions, since ATP is energy.
So to sum it all up,Oxygen (only in aerobic respiration), ATP, light (sun's light), and Carbon are needed to produce energy.
Energy.
Water.
It is same as the animals.It produce energy needed.
Of course they have. They are needed to produce energy
energy sprawl is the amount of land needed to produce clean energy
turbins and nuclear rods
A molecule needed by all living things to produce the energy needed for staying alive. It is used in the process of respiration to produce this energy in all living organisms.
Some sources of energy are described as dilute. This means that large amounts are needed to produce small amounts of useful energy.
No, they don't. If a cell is to continue living it has to continue to produce the energy needed to sustain its activities.
it can produce energy and blow clouds full of rain to where it's needed
Because of the chemicals needed to produce energy.
Fermenation basically regenerate NAD+ from NADH, which is needed to produce more ATPs.
