Trees are the producers of the environment who can undergo the process of photosynthesis. The process of photosynthesis involves the conversion of carbon dioxide and water chemically into glucose and oxygen in presence of sunlight. This glucose is then metabolized by the plant cells into different compounds like lipid, proteins, carbohydrate and different others. These compounds make up the plant body which makes the plant grow into much bigger plant. This makes the mass of the plant increase. Thus, the plant which was planted 10years ago gathered the mass from the environment and converted them into body building products which increased the plant mass by 250kgs.
the length of a cobra doesn't help with the study of life. The moon doesn't either because there is no life on the moon. And how fast the earth rotates is more of a earth science question. I hope this somewhat helps
