2£®________ |
|
out of the water. But water can run out of oxygen, |
3£®________ |
|
just like air can. So fish can suffocate(ÖÏÏ¢) in |
4£®________ |
|
water£which means they can drown! |
¡¡ |

These drownings occur most often in small ponds |
¡¡ |
|
that dries up. All the fish in the pond are crowded |
5£®________ |
|
into the remaining water, which they use up all the |
6£®________ |
|
oxygen in the water, then drowned. Fish can also drown |
7£®________ |
|
if its gills are damaged. Weather conditions also cause |
8£®________ |
|
drownings. When oxygen supply in the water is very |
¡¡ |
|
low the fish raise to the surface and suck air. But |
9£®________ |
|
in cold weather, when the surface is freezing, the |
10£®________ |
