Final answer:
Proper ventilation in animal rooms helps prevent the accumulation of waste gases such as carbon dioxide and sulfur dioxide.
Step-by-step explanation:
Proper ventilation in animal rooms helps prevent the accumulation of waste gases such as carbon dioxide and sulfur dioxide. These gases are released by the animals as they breathe and produce waste. Ventilation ensures that fresh air is continuously brought into the room, allowing the waste gases to be expelled and replaced with oxygen-rich air.
