a striking example is the radiation, begin in the paleogene periods of basal mammalian stuck into form adapted to running ,liping, flying, and swimming.
A.) Viruses
All cells are living things.
Viruses does not count as a living thing AND does not have the genetic makeup to be a cellular organism.
After a caterpillar eats a leaf, it can convert the chemical energy into mechanical energy to help it build a cocoon.
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.
<span>It's Denitrification: In the absence of oxygen bactaria break down nitrates releasing nitrogen back into to the atmosphere and using the oxygen for their own respiration</span>
