Question

Which of the following statements best describes the interdependence between photosynthesis and cellular respiration?

A
Consumers depend on the nitrogen gas that plants release into the atmosphere to make macromolecules, like DNA. Consumers then utilize macromolecules, like DNA.

B
Plants depend on the carbon dioxide that consumers release into the atmosphere to obtain energy and carbohydrates. Consumers rely on the oxygen released by plants, and the carbohydrates stored in plants’ biomass, to obtain nutrients and energy.

C
Consumers depend on the water vapor released during photosynthesis by plants to obtain energy stored in the form of carbohydrates. Plants break down the carbohydrates stored in consumers’ biomass as a means of obtaining energy.

D
Plants rely on the oxygen released through the process of respiration by consumers. Consumers replace the oxygen released through respiration by consuming plant material.

Answer 1

Answer is B.

Plants are photosynthetic autotrophic organisms. They require carbon dioxide and water to make carbohydrate in presence of sunlight. Plants rely on carbon dioxide which is released during cellular respiration by consumers and plants. Consumers rely on plants for the supply of oxygen to carry out cellular respiration. Oxygen is release as by-product during photosynthesis.
