After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide from the body
Answer:
Fossils can be described as the prints of dead animals or plants in sediments. It can take millions of years for a fossil to be formed.
The conditions required for a fossil to form are :
An organism should be buried rapidly after death.
The organisms should not be subjected to the natural process of decay. It should be buried in an ample amount of sediments.
It should be buried in water that is enhanced in minerals.
There are more chances for a fossil to be formed if an organism dies in water and is buried in sediments or muds.

Photosynthesis is the process by which green plants capture the energy from the sun and utilize it to manufacture their own food. The balanced equation for the photosynthesis process is as follows;
6CO2 + 6H2O = C6H12O6 + 6O2
This equation means that, carbon dioxide react with water in the presence of energy of the sun to give carbohydrate and oxygen.
