c. Water changes to yellow as lots of carbon dioxide is produced by the elodea as a result of cellular respiration.
d. Water changes to yellow, this is because more carbon dioxide is produced by both the snails and elodea
Explanation:
The type of relationship that is between snails and elodea is a symbiotic type of relationship because the snails feeds on algae and produces carbon dioxide which the elodea takes in. When elodea undergoes photosynthesis, it produces oxygen the snails uses this oxygen during respiration.
