Final answer:
A dog contributes to the carbon cycle by releasing carbon dioxide through respiration and depositing carbon in the geosphere.
Step-by-step explanation:
A dog contributes to the carbon cycle in two ways:
- It releases carbon dioxide in the atmosphere through respiration, just like humans. This is a natural process that occurs when dogs breathe in oxygen and exhale carbon dioxide.
- In addition, a dog can contribute to the geosphere. When a dog eliminates waste, such as through feces, it contains carbon. Over time, this carbon can enter the geosphere, which is the Earth's solid outer layer.
