EVERYDAY SCIENCE

Detailed explanation-1: -Earthworms breathe in the same way as their aquatic ancestors. They don’t have lungs, but instead breathe through the skin.

Detailed explanation-2: -Earthworms need oxygen just like humans, but they don’t have lungs like we do. They have a special skin that allows them to “breathe” oxygen right through it. How does this work? It has to do with a science concept called diffusion.

Detailed explanation-3: -Because their skin is gas permeable. Their skin is moist, and cutaneous respiration is the process of breathing via the skin.

Detailed explanation-4: -They require oxygen to survive just like us, but they don’t breathe through their mouth or their nose either (they don’t have one!), they breathe through their skin. This is why it’s important your worm farm is kept moist as they require moist skin to allow dissolved oxygen to pass through into their bloodstream.

Detailed explanation-5: -Earthworms do not have lungs; instead, they breathe through their skin. Their skin needs to stay moist to allow the passage of dissolved oxygen into their bloodstream. Earthworm skin is coated with mucus, and they need to live in a humid, moist environment.
