Since mass is conserved, what is a plant that grows in soil?

The plants that grow in the soil are actually the result of conservation of mass, but the energy consumed by seed growth and germination is not single. But if you look at it as a whole, it is true that energy is conserved.

Those who ask such questions are clearly ignoring a very important point. That is, most of the nutrients and water necessary for the germination of seeds are actually stored in the seeds themselves。Secondly, the questioner did not look at the germination of seeds from a macro perspective, ignored the process of water absorbed by the seeds from the outside world, and ignored the heat generated by the reaction of the seeds' aerobic respiration, so he asked this question.

We often have the experience of putting a soybean seed in a dive at a suitable temperature and seeing the soybean sprouts produce in a few days. This is the process of seed germination, and in order to understand this problem, we must first understand the process of seed germination.

If a seed wants to germinate, it needs several conditions, one is the right temperature, and the other is sufficient water. That's why in the spring there is a revival of everything. In spring, the temperature is suitable, and there is enough moisture in the air for most plant seeds to germinate and regenerate.

When a seed is underground, if the temperature is right, then the internal cells of the seed will be activated, and if there is enough moisture in the air, then the epidermis of the seed can absorb the moisture in the air little by little, and prepare for germination. When all these conditions are satisfied, the seed has enough conditions for development, generally in the endosperm of the seed contains a large number of nutrients, in the process of development, the seed in the process of development, by absorbing oxygen and water in the air, using the nutrients in the endosperm to carry out aerobic respiration, growth and development.

From the perspective of energy, the seeds absorb oxygen in the air, consume energy, and release energy at the same time as aerobic respiration, which is in line with the conservation of energy. From the point of view of quality, although the seed only consumes its own endosperm, it grows shoots of greater quality, but we ignore the quality of water and oxygen absorbed from the air, so on the whole, the mass is also conserved. Therefore, the germination process of the seeds is in accordance with the conservation of mass.

The law of conservation of mass is the law of nature, and the growth of plants does not violate this natural law, and the growth of plants is not only the soil, but also fertilizers, rain and snow and nutrients in the air.

The plants that grow in the soil are made up of the mass of air and water absorbed by their seeds.

The soil will hold the roots of the plants in place and store the water between the soil grains for them to use. At the same time, the soil is home to a large number of microorganisms. In just one cubic meter of soil, there are more than 10,000 species of bacteria and fungi, as well as 100 to 1,000 species of invertebrates such as earthworms.

They will decompose dead animals and plants and turn them into nutrients such as phosphorus, potassium, and iron, which can be reabsorbed by the plants. Skinning our vital nutrient cycle is the foundation of terrestrial ecosystems. Nutrients from the soil also flow into rivers and oceans with rainwater, nourishing freshwater and coastal ecosystems.

It is formed by the decomposition of humus by microorganisms in the soil. These are the ingredients that are less available in the water-wide plum cultivation method. Even if there is fertilizer for water supply to grow plants.

Most only provide minerals. Furthermore.
