Question

what is a carbon footprint?

a. the amount of oxygen released by a plant

b. the amount of carbon inside a persons body

c. the amount of greenhouse gas released by a person

d. the amount of carbon dioxide released by a plant

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Plants release oxygen during photosynthesis, but this is not a carbon footprint. A carbon footprint relates to greenhouse gas emissions, not oxygen release by plants. Eliminate A.
• Option B: A carbon footprint is about emissions, not the carbon content within a person's body. Eliminate B.
• Option C: A carbon footprint is defined as the total amount of greenhouse gases (including carbon dioxide, methane, etc.) released into the atmosphere as a result of the activities of a particular individual, organization, event, or product. This matches the definition.
• Option D: Plants absorb carbon dioxide during photosynthesis and release oxygen. The release of carbon dioxide by a plant is not what a carbon footprint is about. Eliminate D.

Answer:

C. The amount of greenhouse gas released by a person
