If the population of rabbits in this ecosystem decreased dramatically because of certain environmental changes, which organisms’ food supply would decrease? A.
owl and snake
B.
jackal and wildcat
C.
green plant and mouse
D.
goat and wildcat

A. Owl and Snake

Explanation:

A green plant cannot eat a rabbit. Neither can a goat.

B. could be the answer but I believe that A. is the answer because I'm positive that those animals eat rabbits.

Hope this helped :)

explanation:

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.
