<u><em>Phosphorous – 32

<u>Answer:</u> <em>Phosphorous – 32
</em>
<u>Explanation:</u>
Radioactive dating is the process of determining the age of the rocks or other minerals using the radioactive isotope of the element. Several isotopes of an element are used for the dating purpose such as carbon-14, potassium-40 and rubidium-87.
Potassium is generally used with argon for determining the concentration of potassium in the mineral. Rubidium-87 is used with strontium to determine the age of the rock. Carbon-14 is used to date the objects that were the part of living organism.
The answer is <span>D) phytoplankton-zooplankton-jellyfish-fish-shark
Phytoplankton could produce its own energy using photosynthesis process before they got eaten by zooplankton.
And there are some species of shark and jellyfish that choose fresh water as their habitat.</span>
