Answer:
The correct answer will be- Crop rotation
Explanation:
When the growth of a type of crop which uses soil nutrients in abundance and then growing another crop in the same filed led to the decrease in the production of the next crop.
Thus farmers adapted to avoid such farming practices and developed a new practice which allowed the land to become fertile again so that the growth of next crop will not be affected.
The practice involved the planting of a crop on a piece of land then leaving the soil ploughed and unsown for a longer period of time and growing corp on another piece of land allowing the time to restore the nutrient content. This practice is known as "crop rotation".
Thus, crop rotation is the correct answer.
<span>Lithosphere includes all the Earth known to us: the mountains, the ground we walk on, etc. It's solid - else we would not be able to walk on it! the more inner layers of Earth are liquid, but lithosphere, the outermost layer is solid. The tectonic plates are not floating on the lithosphere - they form the lithosphere! So the correct answer is A - it is solid and composed of crust and upper mantle (outer later)</span>
male gametes that contribute genetic information (DNA) but few or no nutrients to the offspring. the nuclei of the egg and one sperm unite to form the zygote; the other sperm nucleus fuses with the two polar nuclei, forming a triploid (3n) cell. so, a, I believe.

Answer:
Forests are helpful, They provide clean oxygen for us. Imagine life without forests. Now that wouldn't be good for the animals would it? Many animals are very important to the earth. Forests nurture the soil, Forests absorb carbon, Forests provide food for millions, Forests are natural aqueducts, Forests host 80% of Earth's biodiversity. There are many reasons why we need forests. Overview, Forests are vital to life on Earth. They purify the air we breathe, filter the water we drink, prevent erosion, and act as an important buffer against climate change.
