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.
Cellular respiration is a catabolic process.
The first step of the process is the digestion.
while respiration implies air, fermentation is an anaerobic (no oxygen) process.
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.
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.
