Ice is less dense than water so it floats on water. This is useful because it insulates the remainder of the water but also means that aquatic life will not die as they would if water froze upwards.
A pond freezes from the bottom because water is most dense at around 4 degrees Celsius. When the top layer of water cools and freezes, it becomes less dense and remains on top, insulating the warmer water below. This allows the colder water to continue freezing from the bottom up.
in the middle because tthere is more water.
The ground stays warmer. so the top is frozen first because it comes in direct contact with the cold air, and the bottom is in closer contact to the warmer earth.
Aquatic life is possible in a frozen pond because only the top of the pond is frozen. The fish live down at the pond bottom, where it is warmer than the top.
Fish generally go down to the bottom of the pond where the water does not freeze and sort of hibernate for the winter. That is why it is important to make your pond so deep that the water will not freeze all the way to the bottom. (www.rosepond.com)
Every animal in the pond is part of the pond food chain. The animals at the top of the chain are large fish, and the animals at the bottom are bacteria and single-celled organisms.

Aquatic life is benefited by the anomalous expansion of water because the water freezes top to bottom, not bottom to top. If it froze bottom to top, then the aquatic life would be pushed up, up, up, towards the surface of the water. Since it goes top to bottom, and the water at the bottom remains at 277K, the Aquatic life can survive there.
They screw into the top and bottom plates instead of nailing in.

No, there is not.
