Answer
Large multicellular organisms require lungs to increase gas exchange.
Explanation
## Step 1:Large multicellular organisms, such as humans, require lungs because they have a high metabolic rate. This means they need a lot of oxygen to maintain their bodily functions. ## Step 2:The lungs provide a large surface area for gas exchange. This is important because it allows for a large amount of oxygen to be taken in and carbon dioxide to be expelled efficiently.## Step 3:The presence of lungs in large multicellular organisms helps to increase the rate of gas exchange, not reduce it. This is because the lungs are designed to maximize the diffusion of gases.
