How Trees Work to Balance the Earth’s Gases

Scientists believe that life on Earth began in the ocean, but once single-celled organisms made their way onto land, they needed to develop ways to survive without being in water all the time. Trees have been around since the earliest times of Earth’s history, with fossil records dating them back hundreds of millions of years. In fact, because trees have been on Earth for so long, many scientists believe that trees may be necessary for life to continue as we know it. They believe this because many of trees’ processes are intertwined with balancing some of the gases in our atmosphere, including carbon dioxide and oxygen.



Trees work to balance the earth’s gases. They take in carbon dioxide and release oxygen into the atmosphere. In this way, trees help to balance the gases and energy being cycled on Earth. Trees also release water vapor in a process called transpiration which also helps with balancing gases within our atmosphere. This all helps for a sustainable ecosystem and healthy life cycle for humans, animals, and plants living on this planet.

How Trees Take in Carbon Dioxide

Breathing in carbon dioxide, trees use chlorophyll and sunlight to release oxygen. Carbon dioxide is a by-product of photosynthesis, and through this process, trees can take in as much as 100 pounds (45 kilograms) of carbon dioxide per year. The tree releases water vapor through a process called transpiration. Transpiration is when water from the soil moves up into a tree’s leaves and is released back into the atmosphere as water vapor.

How Trees Release Oxygen

Trees release oxygen through a process called photosynthesis. Photosynthesis is when sunlight interacts with carbon dioxide and water in the air, releasing oxygen and producing carbohydrates. When trees produce these carbohydrates, they use up some of their stored energy, so they need nutrients from the soil to keep going. Why do leaves give off oxygen? To eat, trees go through a process called photosynthesis. To do this, their leaves pull in carbon dioxide and water through tiny pores, called stomata, and use energy absorbed from the sun to turn the CO2 and H2O into sugars. During that process, the tree releases 02, which is oxygen, from the leaves’ stomata.

How Trees Help to Balance the Earth’s Gases

Trees hold the key to survival on Earth. The trees take in carbon dioxide and release oxygen into the atmosphere. In this way, trees help to balance the gases and energy being cycled on Earth. They also release water vapor in a process called transpiration. This way, trees not only balance out gas levels but also help regulate moisture levels which are crucial for our planet. If we don’t plant more trees soon, then it could be catastrophic for us all. Scientists have been working hard at finding new ways to protect the environment, but it’s up to each one of us to do our part as well.

Plant Trees

We will not be able to survive without trees. They are a vital component of our ecosystem, and we need them for survival. Without trees, there would not be enough water in the environment, and life would eventually die off. Plant a tree, don’t cut it down. Maybe the next time you have an opportunity to save a tree, you will.–MM
