1. how can the presence of coal-fired electricity plants can affect the ability of lakes to support life.

2. Suppose that there has been a sudden growth of algae in a lake in cottage country.

(a) Suggest three possible causes for this situation.
(b) Explain what could happen in the lake.


Sagot :



Algae grow when they have the right conditions such as adequate nutrients (mostly phosphorus but nitrogen is important too), light levels, pH, temperature, etc. Generally the amount of phosphorus controls the amount of algae found in a freshwater lake or water body. The more nutrient-enriched a lake is, typically the more algae in the lake.
