Answer:
from the splitting of water molecule.
Explanation:
The splitting of water molecules by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis of enzymes of Photo system 11.
It involves the splitting of water molecules into;
hydrogen ion/protons.
Oxygen
and electron.
<u> Oxygen is the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.
the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02 to form carbohydrate in light independent reaction
Answer:
c. fittest descent with modification
Explanation:
Evolution can be defined, in a nutshell, as the process of variation and adaptation of populations over time, and may even cause the emergence of new species from a pre-existing one. In short, evolution is the process that gives rise to a fittest descent with modification. Thus, the great diversity of organisms present on our planet can be explained through this theory.
As we study evolution, we realize that the life forms we know today are not the same as those that lived thousands of years ago. This means that species have an evolutionary history and that many changes happen to them until there are the characteristics we observe today.
Species, therefore, are not fixed, have undergone changes throughout their history on the planet and continue to change. Man, for example, did not appear on earth as we see today, as there were several ancestral species.
C. consumers depends upon producers for food
