Acid Attacks
This lesson looks at the effect of pH in a pond on the organisms that live there.
The pH of ponds can differ depending on their location and the source of their water. pH levels are not static within ponds, however, and can fluctuate throughout the course of a day. The change in pH in a pond does not need to be large for the organisms living in it to be affected in quite significant ways.
