d
Respiration

Answer 1

(D) Respiration

Step-by-step explanation:

To carry out the process of respiration every cell requires oxygen and glucose. The cellular respiration is a process by which the organism uses oxygen to produce carbon dioxide and water as their by-products. These end products are also known as waste products. The energy released in the process is used in many functions like movement and reproduction.

CH₂O + O₂⇒ CO₂+ H₂O+ Nutrients+ Chemical Energy

Answer 2

D.Respiration

Explanation

Organisms produce carbon dioxide as a by product when they undergo the process of cellular respiration.During cellular respiration,animal cells combe the oxygen and food molecules to release energy needed vfor growth,reproduction and functionality.The carbon dioxide is released as a waste.
