Atp and cellular respiration
ATP is an important macro molecule to cells. ATP is the primary energy currency to cells in organisms. ATP stands for adenosine triphosphate. ATP is energy that widely distributes energy energy to any organism. All living thing needs ATP in order to live. ATP consists of a nucleoside adenosine and a tail that consists of three phosphate. ATP is also a energy bank for living things. If one of the phosphates break the bond, ATP turns into ADP. ADP stands for adenosine diphosphate. In order for ADP to turn back into ATP, glucose needs to make another bond with ADP, turning it back to ATP. Earthworms get ATP from the organisms they decompose from.
How do earthworms obtain oxygen?
Oxygen in necessary for earthworms because it makes them stay alive. Oxygen doesn't go into the earthworm. Instead of having lungs, earthworms breath through their skin. But its not only oxygen that passes through the skin. Carbon dioxide also passes through the skin by diffusion. So the earthworms get rid of Carbon dioxide by letting it pass the skin. But if the earthworm wants this to happen, it needs the skin to be moist for diffusion to happen. The way that an earthworm can get moist is by the body fluid and mucous released on the skin. This means that earthworms can only in in dump or moist soil. This is also a reason why they can't go outside of the soil. They can only go outside at night. The reason why is because the air at night is low for them. (1) If they don't get moist and become dry, they can suffocate. The mucous in the earthworms skin helps the earthworm take the oxygen into the body and goes to the circulatory system were the oxygen goes to the heart. Then the heart pumps out the oxygenated blood to the head are of the earthworm. Every time that the earthworm moves, the blood is pushed back as well as carbon dioxide. Then carbon dioxide is released and back in the the earthworms skin. This process is good for the plants and soil.(2) The way that earthworms gain oxygen is by moving in the soil. Every time they move, they get oxygen. The oxygen is in an air form not in a water form.

GAs Exchange/REgulation
The way that earthworms exchange gases is through their. Every time they breath, oxygen goes inside the segmented earthworm, while CO2 is released from the body. THe oxygen goes in the segmented body of the earthworm, then travels to the vessels till it final reaches to the five hearts. The five hearts will send oxygen to every segment in its body. This makes the earthworm breath and move in a steady pace. When the earthworm wants to regulation its temperature, it either goes underground or outside. It would go underground if the temperature outside is too warm and the earthworm would come outside if the temperature underground is too warm or cold.
