? What is the role of the earth in the life of a tree?
Answers
Answer:
Trees provide oxygen and limit carbon in the atmosphere. They reduce air pollution, provide food and shelter for wildlife, minimise erosion and maintain healthy soil, increase rainfall, and absorb sunlight as energy. ... They effectively absorb harmful gases such as sulfur dioxide, carbon monoxide and nitrogen dioxide.Trees are vital. As the biggest plants on the planet, they give us oxygen, store carbon, stabilise the soil and give life to the world's wildlife. They also provide us with the materials for tools and shelter.Trees protect the earth from soil erosion, fires, flooding, and wind. ... They use a living fence technique which has proven especially useful in providing in creating a green wall to improve their soil, provide a boundary, keep livestock out, and absorb and redirect heavy rains.FILTHY AIR: Without trees, humans would not be able survive because the air would be unsuitable for breathing. If anything, people would have to develop gas masks that filter the little oxygen that would be left in the air.Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.When trees are starved of water, they certainly suffer and make a noise. Unfortunately because it is an ultrasonic sound, too high for us to hear, it goes unheard. ... Inside tree trunks are bundles of specialized tubes called xylem, which lift liquid to the highest leaves and branches.
