Nervous system began to form in the womb of mother when the foetus is about 2 weeks !
The migrated species prevail in the conditions in that area.
The two cycles are photosynthesis and cellular respiration.
Cellular respiration releases energy stored in glucose (during photosynthesis). Most of this energy is transferred to an energy molecule that can be used by all cells: ATP.
