Trees are essential to life on Earth, providing us with oxygen and cleaning the air of harmful gases. But how do trees produce oxygen? Through a process called photosynthesis, trees use energy from sunlight to convert carbon dioxide and water into glucose. This glucose is then broken down to release energy that boosts the tree's metabolism. In the process, oxygen is released into the atmosphere through small openings in the leaves called stomata.
Tree roots also need oxygen to grow and thrive. The amount of oxygen available in the soil depends on its type and compaction level, with the greatest amount found close to the surface. Deciduous trees, such as chestnut, oak, poplar and maple, lose their leaves in autumn and take a kind of winter vacation. The power of a single tree is remarkable; it can provide oxygen for up to four people! When people breathe in oxygen and breathe out carbon dioxide, trees absorb the carbon dioxide and give us oxygen in return.
Tree roots grow horizontally from the base of the tree, so it's important to have programs that replace trees when they are lost or damaged. We should also study ways to improve trees' fire resistance and carbon absorption capacity. Planting a tree in your garden and encouraging others to do the same is one of the best things you can do as a responsible citizen of the planet. Trees produce their own food through photosynthesis, using energy from sunlight, water (from roots) and carbon dioxide (from air) to create sugar that is used as fuel for the rest of the tree. By understanding how oxygen helps trees grow, we can better appreciate their importance in our lives.
