It will take in carbon dioxide from the atmosphere.
Its feces will contain carbon that will enter the geosphere.
It will convert carbon to a form that will be used by plants for energy.
It will decompose the body of plants to release carbon dioxide.

Answer 1

A dog contributes to the carbon cycle by releasing carbon dioxide through respiration and by depositing carbon in its waste.

Step-by-step explanation:

A dog contributes to the carbon cycle in two ways:

1. It will release carbon dioxide in the atmosphere through respiration. Like humans, dogs inhale oxygen and exhale carbon dioxide as a waste product of cellular respiration.
2. Its feces will contain carbon that will enter the geosphere. When a dog defecates, the carbon in its waste can enter the geosphere through decomposition and eventually become part of the carbon cycle.
