Question

6. 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.

Answer 2

A lack of dissolved oxygen is the most

common cause of fish kills in ponds. This

occurs frequently when aquatic plants

and algae die in the summer or when

they are treated with aquatic herbicides.

Fish kills due to low Oxygen are most

common during hot, dry spells when

algae grow and then die quickly.
