Answer:
Organic fertilizers continue to improve the soil long after the plants have taken the nutrients they need. Therefore, the longer your soil is fed with organic fertilizers, the better its composition and texture. So, while inorganic fertilizer is cheaper in the short term, it adds less to the soil in the long term.
Pretty sure yeah. When plants have strong roots they can hold the soil firmly in place, even during bad storms.
Basically, what happens is that, because oxygen is really important to life, the cells go into anaerobic metabolism. Then they get depleted of the nutrients and they start dying.
Viruses are not alive. Although they sort of “hack” a host’s cells and reproduce, they do not breathe or move on their own. A virus will sit on a counter forever if it’s untouched. Viruses are spread by physical contact, not because they can move around on their own.
Although viruses can attack and hack, and use your cells to reproduce, they are programmed to do so.
Cells are very much alive, while viruses are not.
