What happens when the lynx population rises ?

Explanation:

hare numbers start to decline, lynx continue to eat well because they can easily catch the starving hares. When hares become scarce, lynx numbers also decline. ... Low lynx population levels last for three or four years. When hares become plentiful again, the lynx population begins to increase as well.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
