Solution
Shallow ponds are not very deep, the area of water measures only a short distance from the top to the bottom.
Animals like fish in shallow ponds die during summer because the water of shallow ponds evaporates in summer.
This process (evaporation) is fast in hot areas leading to a shortage of water in ponds and sometimes no water in ponds leads to the death of aquatic animals like fish.
