In the light, snails primarily give off oxygen as a byproduct of photosynthesis when they are associated with symbiotic algae or when they are in environments where photosynthetic organisms are present. However, snails themselves do not perform photosynthesis; instead, they respire like other animals, consuming oxygen and releasing carbon dioxide. Therefore, in the context of their own metabolic processes, they primarily emit carbon dioxide.
