In earthworms the gaseous exchange takes place from their skin
They perform cellular respiration but not photosynthesis.
Earthworms exchange oxygen and carbon dioxide through their skin. They absorb oxygen from the air and release carbon dioxide into the environment through their moist skin. This process is called cutaneous respiration.
their large surface areas of moist skin, have no any specific organ for respiration.
The first step of the process is the digestion.
Digested proteins are converted to new proteins by the process of synthesis in earthworms. Earthworms will feed on a large variety of decaying organic matter as well as manure, compost, and shredded cardboard, wood, or papers.
Cellular respiration is a catabolic process.
while respiration implies air, fermentation is an anaerobic (no oxygen) process.
anaerobic respiration
Earthworms in the class oligochaeta, which is in the phylum annelida. Ecdysis occurs in the phylum arthropoda. My guess is that earthworms' cuticles undergo a process closer to our skin's than ecdysis.

Earthworms exchange gases through their skin, which is permeable to oxygen and carbon dioxide. As they burrow through the soil, oxygen from the surrounding environment diffuses into their body, while carbon dioxide produced from their metabolism diffuses out. This process is facilitated by moisture on their skin, which aids in gas diffusion. Therefore, maintaining a moist environment is essential for effective respiration in earthworms.
