Animals obtain energy from the processes of ingestion, digestion, and secretion. Excretion of wastes is not required.
Excretory system
The process by which cells use energy to maintain life activities would be respiration.
The advantage is that ammonia (NH3) is not converted in Ammonotelic excretion. Fish can excrete ammonia through gills because there is a lot of water to dilute it in without causing damage to their cells. In Uricotelic excretion, NH3 has to be converted to a solid form via a complex and ATP-costly route. So Uricotelic excretion takes a lot more energy than Ammonotelic excretion.
cellular respiration
Many people confuse the process of excretion with the removal of waste products of digestion. Excretion, however, is actually the removal of all the waste products produced by the cells of the body.
I think for me the process of excretion with the process of defecation is by the process of excretion with the process of defecation. Therefore the defecation is the process of excretion by the process of defecation. Some says excretion is the process with the defecation process. That's why the organ contrast the process of excretion with the process of defecation.
Yes excretion is a life process. It's the removal of waste.
When plants transpire, it is the process of excretion for them. They use the carbon dioxide from animals to make energy, and let out water vapor, or transpire, as a result.

Cells make and use energy through the process of photosynthesis. This process both creates energy and uses energy to deliver the nutrients.
Excretory system
Excretion means getting rid of, the process is the process of getting rid of your excretorial wastes, or your stool.
The ATP molecule is not used in excretion process. This is a molecule that will be used in cellular respiration to store energy.
Photosynthesis
The process by which cells use energy to maintain life activities would be respiration.
No, ATP is the energy molecule in cells.
