Question

Which of these best describes the role of plants in the carbon-oxygen cycle? A. to absorb oxygen from the atmosphere and release carbon dioxide into the atmosphere B. to absorb carbon dioxide from the atmosphere and use it to make sugar C. to absorb oxygen from the soil and use it to make carbon dioxide for sugar production D. to absorb carbon dioxide from the atmosphere and release it back into the atmosphere

Answer 1

It's B because plants use carbon dioxide, water, sunlight and some minerals from soil in order to make food or glucose and releases oxygen as a waste product.

Answer 2

The correct answer is B. To absorb carbon dioxide from the atmosphere and use it to make sugar.

Explanation:

The carbon-oxygen cycle refers to a natural cycle in which both carbon dioxide and oxygen move through different biotic and abiotic factors. This cycle is necessary for life on Earth as organisms such as plants require carbon dioxide, while others such as animals require oxygen to live. In the case of plants, they play an important role in this cycle as they absorb carbon dioxide from the atmosphere that is the result of animals breathing and use this carbon dioxide to produce their own energy in the form of glucose or sugar while releasing oxygen to the atmosphere. According to this, the option that describes the role of plants in the carbon-oxygen cycle is option B.
