Step-by-step explanation:
Photosynthesis is the process by which green plants manufacture they own food using carbon dioxide and water in the presence of sunlight and chlorophyll.
During photosynthesis, glucose and oxygen are produced as follows; 6CO2 + 6H2O → C6H12O6 + 6O2
This makes photosynthesis a process that is very essential to animal life since animals breathe in oxygen and exhale carbon dioxide.
Through the process of photosynthesis, plants furnish an oxygen rich air without which animals can not breathe. This makes ambient air fresh and fit for animals to breathe in. Hence, photosynthesis is a very essential process for the survival of animals.
