Answer:
![\boxed {\boxed {\sf Photosynthesis}}](https://img.qammunity.org/2021/formulas/biology/high-school/qcnv7p0m54skspxpwqebn9aby3qcaddl2w.png)
Step-by-step explanation:
Photosynthesis is a process that plants, specific types of bacteria, and algae undergo to produce "food".
The equation for this process is:
![6CO_2+6H_2 O + energy \Rightarrow C_6 H_(12) O_6 + 6O_2](https://img.qammunity.org/2021/formulas/biology/high-school/3vkhiidsjnj8msap7s28c6zrdjog3sl9yh.png)
carbon dioxide + water + energy ⇒ glucose + oxygen
Carbon dioxide and water, plus energy from the sun, are turned into sugar and oxygen. The sugar becomes the "food" for the organism and is used in cellular respiration to make ATP/energy to carry out metabolic processes. The oxygen is released as waste, which animals breathe.
So, the best answer is photosynthesis
