Question

Which statement accurately describes an interaction between plants and animals? A. Animals release O2, required for plant survival. B. Animals release CO2, required for photosynthesis. C. Plants provide humans with atmospheric nitrogen. D. Plants provide humans with CO2 for respiration.

Answer 1

The answer is B.

Animals do cellular respiration which requires the intake of oxygen and the output of carbon dioxide. In order for plants to do photosynthesis, they need carbon dioxide to be able to make oxygen for animals to breathe.

Answer 2

B

Step-by-step explanation:

The correct answer in this question is option B:

Animals release CO₂, required for photosynthesis.

While every other statement may be close to the truth, they are not quite correct. For example:

Animals release CO₂ (not O₂) which is necessary for plant survival.

Plants provide humans with O₂ gas (not atmospheric nitrogen)

Plants provide humans with O₂ (not CO₂) for respiration
