Correct answer choice is :
<h2>A) Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.</h2><h2 /><h2>Explanation:</h2><h2 />
Photosynthesis produces the glucose that is utilized in cellular respiration to make ATP. The glucose is then converted back into carbon dioxide, which is utilized in photosynthesis. While water is broken down to form oxygen through photosynthesis, in cellular respiration oxygen is blended with hydrogen to form water.

Explanation:
Adaptation may be defined as the ability of the organism to adapt and survive according to its environment. Physical, physiological and chemical changes occur in the body of organism for the adaptation process.
The evolution of the increase in the size of the animals might also changes their internal physiology. The lungs and digestive tract also evolved as the size of the organism get bigger. The lungs has the alveoli to increase the surface area and inhalation of more oxygen in the body. Digestive system has villi or folds that increases the surface area for digestion and absorption.
Thus, the answer is more branching or folds.
