The Answer would be C. Without plants in the ecosystem, it could not feed. Plants are mainly the only producers that feed 3rd level consumers which feed 2nd level consumers which feed 1st level consumers.
<u>The mass of hydrogen atoms in the sample of water is 3.98g</u>
This can be solved by understanding of Avogadro's number and mole relationship concept.
<h3 /><h3>Avogadro's number</h3>
<u>This is a proportionality that relates the number of particles to the amount of substance in that sample and it is given as </u>
A molecule of water have the chemical formula as HO. This implies that for every 1 atom or molecule of oxygen, 2 hydrogen must be present.
In the question given, we have atoms of oxygen. This implies we must have
Now, let's compare this molar mass - Avogadro's number
molar mass of hydrogen = 1g/mol
From the calculation above, we would have 3.98g of hydrogen present in that particles of oxygen.
