Answer:
In biology, a molecular clock can be described as a method to determine the time for the divergence of species which occurred by the process of evolution.
Explanation:
The mutation rates of different molecules are used in this method. The mutation rates for DNA sequences and amino acid sequences are usually considered. The molecular clock can be used to compare and estimate the splitting of a lineage. For example, by this method, one can interpret when the chimpanzees and humans diverged from each other.

Sun(solar energy)
Explanation:
The sun is the ultimate source of energy in our solar system.
The chemical energy in plants all started out with solar energy from the sun.
During the process of photosynthesis;
- green plants manufactures their food using sunlight.
- in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.
Photosynthetic reaction simply converts solar energy from the sun into chemical energy.
Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.
