Question

What do you think what do you think will happen if all the fish in a pond die how will it affect the pond ecosystem

Answer 1

Answer:

When the oxygen in the pond is used to decompose the dead algae, it is not available for fish and other aquatic life. A die off can be so severe that most of the available oxygen in a pond can be used up in the decomposition process and your fish and other aquatic life will start to die off.
