Question 11 The tropical rainforest is sometimes called the "lungs of the earth" because of the abundance of plant species. Which two atmospheric gasses are balanced by tropical rainforests? water wapor carbon monoxide oxygen nitrogen carbon dioxide 2 pt

## Step 1<br />The question is asking about the two atmospheric gases that are balanced by tropical rainforests. The term "balanced" in this context refers to the process of absorption and release of gases by the rainforests.<br /><br />## Step 2<br />Tropical rainforests are known for their ability to absorb and release gases. They absorb carbon dioxide (CO2), a greenhouse gas, during photosynthesis. This process helps to reduce the amount of CO2 in the atmosphere, which is beneficial for the environment.<br /><br />## Step 3<br />On the other hand, rainforests also release water vapor into the atmosphere. This process is part of the water cycle, which is essential for the survival of all living organisms.<br /><br />## Step 4<br />The balance between the absorption of carbon dioxide and the release of water vapor is what makes tropical rainforests often referred to as the "lungs of the earth".
