Question 1 (Multiple Choice Worth 4 points)

(04.05 MC)
Which statement best describes two paths carbon dioxide can take through the carbon cycle?
The carbon cycle ends when carbon dioxide is released when plants die and decompose.
Diffusion moves carbon dioxide in the atmosphere to the oceans and the sea plants use carbon dioxide for photosynthesis.
O Carbon dioxide travels through the atmosphere through photosynthesis and cellular respiration.
Plants use carbon dioxide to perform cellular respiration and release carbon dioxide as a by-product.

Answer 1

Option 2. "Diffusion moves carbon dioxide in the atmosphere to the oceans, and the sea plants use carbon dioxide for photosynthesis."

Step-by-step explanation:

This statement describes two processes in the carbon cycle. First, carbon dioxide moves from the atmosphere to the oceans through diffusion. Once in the oceans, carbon dioxide can be taken up by sea plants during photosynthesis, in which carbon dioxide is used to make organic molecules like sugars. These organic molecules are then consumed by other organisms in the ocean, and the carbon is passed along the food chain. This process represents one path that carbon dioxide can take through the carbon cycle.
