Природные водоёмы очищаются одновременно разными механическим, физико-химическим и биологическим. Приведите примеры, как они работают? Почему так опасны загрязнения водоёмов, на берегу которых моют автомобили?

Объяснение:

Yesterday, after work, I took my son Peter to the store for a new coat. we were shown a lot of coats. I liked the brown coat . Then we went to another store and bought a toy for our second son and a picture book for our little daughter. And gifts for my wife. It took us an hour and a half to do all the shopping, and we got home at a quarter past eight. at home, the children took our boxes and opened them. They really liked the gifts. The daughter, who likes to go shopping, said that one day she and her mother will also go shopping. We'll buy a new hat for Dad and a new shirt for Peter."
