Actually, it could indeed be the independent variable.
Answer:
Carbon-14 or C-14
Explanation:
Since the isotope is a carbon isotope, it means the the atomic number of the isotope is 6.
The atomic number of an element is the proton number.
Therefore, the isotope has a proton number of 6
Now we need to obtain the mass number of isotope in order to write the symbol of the isotope. This is illustrated below:
Mass number = Proton +Neutron
Proton = 6
Neutron = 8
Mass number = 6 + 8
Mass number = 14
Therefore, the symbol of the isotope is carbon-14 or C-14
Because food and water are resources that are basic needs for all members of the population. When these resources decrease more members of the population will either die or move to another area and the population size will decrease.
Hope this helps!
