Answers
Answer:
animals breathe through either their lungs or gills ( fish) or through their moist skin.
They taken in oxygen which circulates blood in their body and the
carbon dioxide comes out in the same way they taken in oxygenated.

Explanation:
The mechanism by which organisms obtain oxygen from the air and release carbon dioxide is called breathing. But on the other hand respiration is a complex process it includes breathing as well as the oxidation of food in the cells of the organism to release energy. Breathing is a physical process whereas respiration is a biochemical process of oxidation of food. Breathing process involves lungs of the organism whereas respiration involves the mitochondria in the cells where food is oxidised to release energy.
The energy produced during respiration is stored in the form of ATP (Adenosine Tri- Phosphate) molecules in the cells of the body and used by the organism as when required. To understand this we should know the meaning of ADP, ATP and Inorganic Phosphate. ADP is Adenosine Di- Phosphate; ATP is Adenosine Tri- Phosphate and Inorganic Phosphate is a substance which contains a phosphate group made up of phosphorous and oxygen.
(i) The energy released during respiration is used to make ATP molecules from ADP and inorganic phosphate.
This energy is stored in the cells in the form of ATP.
(ii) When the cells need energy, then ATP can be broken down using water to release energy.
hope this helps;)
