How Plants Grow 1 Pages 285 Words

Soil has moisture and nutrients, so it is an ideal place for plant growth. Because the soil is rooted, the plant stands on the ground and can gather the necessary light for life. This will help the plant grow. Fungi and bacteria also live in the soil. They eat dead plants and animals. Cracked substances become food of plants (nutrients). Many animals dig up the ground and house the soil. Large animals use soil to sleep and make teeth for birth. In most cases, small animals live in the soil.蚯蚓 is known for improving soil. This is because the holes they form allow air to enter the soil. Those holes also let water pass

Back to the top Generally, most plants grow by absorbing nutrients in the soil. Its ability depends on the nature of the soil. Depending on its location, the soil contains a combination of sand, silt, clay and organic matter. Depending on the soil composition (soil quality) and its acidity (pH), the extent to which plants can acquire nutrients is determined. The texture of the soil affects the retention of nutrients and moisture in the soil. Clay and organic soils maintain better nutrients and moisture than sandy soils. When water is discharged from sandy soil, it often carries nutrients. This condition is called leaching. When nutrients penetrate the soil, they can not be used by plants.

Imagine that two plants are growing side by side. They compete the sun and the earth everyday. As a plant grows faster than other plants, it grows higher, captures more sunlight, and can absorb more rain. The next day, this extra energy will make plants grow more. This pattern continues until a powerful plant squeezes out the other plants and occupies most of the sun, soil and nutrients. From this point of view, the winning plant has better ability to spread and propagate the seed, so that the seed has a larger footprint in the next generation. This process is repeated over and over until the plants slightly better than the competitors occupy the entire forest.
