Answer:

Air particles are a mixture of solids and liquids that are microscopically tiny and suspended by air currents. It can stay in the atmosphere for a few hours to a month or two. Their constituents can be various harmful substances such as heavy metals - lead, nickel, arsenic, cadmium or polycyclic aromatic hydrocarbons

Explanation:

Air particles, nitrogen dioxide and ground-level ozone are now considered to be the three most polluting substances in human health. Exposure during peak concentration and long-term exposure to these pollutants can cause damage from respiratory distress to premature death.

Directions: identify whether it is biotic or abiotic by writing your answer before the number
BlackZzzverrR [31]
1. Algae- Biotic
2. Abiotic
3. Biotic
4. Abiotic
5. Biotic
6. Abiotic
7. Biotic
8. Biotic
9. Biotic
10. Abiotic
11. Biotic
12. [could be both]

In order to see if something is Biotic or Abiotic, think about whether it’s alive or not.
Dissolve oxygen is just the oxygen levels in the ocean, it’s not really a living thing. While it does effect the environment, it’s abiotic because it isn’t living. Fish, however, are are biotic because they’re alive.

If you’re ever confused, just think about the basic things all living things have, which is cells, and apply it to the question. Does changing weather have cells? Nope. do trees have cells? Yep!

Also, for the Fertile soil, I said it could be both because of what’s in the soil. Fertile soil has biotic factors in it, like dead animal stuff and dead plant stuff. (Anything that was once living, even if it’s dead, is still considered a biotic by the way). I think your best bet would be to put biotic, but I might be wrong
But yeah, in summary, Biotic means living, Abiotic means non living, and in order to see which is which, ask yourself if whatever you’re questioning has cells. Good luck
