What metric unit can you use for amount of water in a pond?
Litres.
How can you found out the amount of solid dissolved in pond water?
To find the amount of solid dissolved in pond water, you can conduct a process called gravimetric analysis. This involves evaporating a known volume of pond water to dryness and then measuring the remaining solid residue. The difference in weight will give you the amount of solids dissolved in the pond water.
Which change in a sample pond water could indicate that heterotrophic microbes were active?
a decrease in oxygen level
Are water lilies good for ponds?

Which effect does a decrease in sunlight have on a pond?
.
Does vinegar harm pond goldfish?
