It should be noted that the graphs illustrated how different PH affect the population of the species.
<h3>What is PH?</h3>
It should be noted that pH simply means the measure of how acidic or basic water is. It can be deduced that the range of the pH is from 0 - 14.
From the complete question, the graphs illustrated how different PH affect the population of the species. When the pH is either too low or too high, the aquatic organisms living in it will die.

This happens because taproot formation is impossible, so trees developed shallow root beds.
Permafrost is soil that has a temperature below 0 °C (for about two years) and forms a solid matrix which can extend to a depth of hundreds of meters. Because of this structure the permafrost prevents trees from developing deep root systems. As a consequence, the shallow root bed of trees such as black spruce, causes them to lean or even fall.
