I think ionization energy is the energy required to remove an electron from a neutral atom. It is the amount of energy that is required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation. Atoms and molecules have this measurement, which refer to the energy it takes for all atoms in one mole of a substance to each lose one electron.
        
             
        
        
        
Answer: Energy is produced by respiration because its stored within the cells in the form of ATP (Adenosine Triphosphate) .
Explanation:
I'm pretty sure that's it.

The correct answer is all of these.
Matter and energy on Earth are never destroyed or created out of nothing, but just transferred or converted to another form.
 The inorganic matter is transferred to the living things from the physical environment by many biological processes like photosynthesis ( CO2), nitrogen fixation, absorption of the minerals by plant roots and many more.
Matter can then be transferred between different organisms through the food chain.
Eventually, the matter will return to the physical environment when organisms decompose and the cycle will start again.
        
             
        
        
        
He first divided all living organisms in 2 groups
Animal or Plant
He then put these into subgroups
Animal subgroups: land, water, air
Plant subgroups, small medium or large
Not a very specific approach to taxonomy but it was used for well over 100 years
        
             
        
        
        
False 
Mutations can form and be predicted 
Depending on the situation
