D) Carbon dioxide is needed for respiration and oxygen is a waste product.

Answer 1

The answer is letter B. Oxygen is used for respiration and carbon dioxide is a waste product. The animals and plants they both require oxygen and produce carbon dioxide. Plants because they make Oxygen and food for the animal and mammals that are dependent upon them for their own food. They also produce oxygen.

Answer 2

The correct answer for the question is B; Oxygen is used for respiration and carbon dioxide is a waste product.

Step-by-step explanation;
Plants and animals use the process of respiration to produce energy which is used to fuel normal activities such as growth and movement. The process uses oxygen to break down nutrients such as carbohydrates, fats and proteins, and release energy needed by the plants and animals; but, also creates water and carbon dioxide as byproducts.
Carbon dioxide is a by product of the process of respiration, a chemical reaction that plants and animals use to produce energy they need to carry out day to day activities.
