The chemical a0 enables a process called a1 that is the ultimate source of all food energy on earth.

The chemical chlorophyll enables a process called photosynthesis that is the ultimate source of all food energy on earth.

Explanation:

A very important characteristic of chlorophyll, is its ability to transform sunlight energy into chemical energy, this is through the process of photosynthesis, in which the energy absorbed by chlorophyll transforms carbon dioxide and water into carbohydrates and oxygen. For this reason, we can conclude that chlorophyll allows a process called photosynthesis that is the ultimate source of all food energy on earth.
