Question

Which statement best describes two paths carbon dioxide can take through the carbon cycle? Carbon cycle ends when carbon dioxide is released when plants die and decompose. Carbon dioxide in the atmosphere is carried through the ocean with precipitation and plants also use carbon dioxide in the atmosphere for photosynthesis. 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

Carbon dioxide plays an important role in carbon cycle. Carbon dioxide is used by plants in the process of photosynthesis to make food. The food is eaten by animals to gain energy and performs cellular respiration which releases carbon dioxide back to the atmosphere. This is the process of biological carbon cycle.

In geological carbon cycle, carbon dioxide enters the ocean by precipitation and combines with elements like calcium forming a compound and becomes the component of living organisms. Carbon compounds settles in the ocean when the organisms die.

Answer 2

Answer:

The two paths that carbon dioxide can take through the carbon cycle are carbon dioxide in the atmosphere is carried through the ocean with precipitation and plants also use carbon dioxide in the atmosphere for photosynthesis

Explanation:

These paths/answer chosen represents both the biological and geological paths through which carbon dioxide can take through the carbon cycle.

plants take carbon dioxide released by animals into the atmosphere for photosynthesis (biological carbon cycle)

while carbon dioxide enters the ocean through precipitation and can get back to the atmosphere through volcanic eruptions (geological carbon cycle)
