Summary Introduction
To review:
The cause for an algal bloom and its consequences.
Introduction:
When the algal growth increases and get accumulated in a freshwater or marine ecosystem is known as algal bloom, it can adversely affect the lifecycle of other aquatic life. Eutrophication is a natural process that occurs gradually over time but can be accelerated by the anthropogenic activities. It leads to an algal bloom.

State whether the following is True or False of the process of eutrophication from the overuse of fertilizers.
Group of answer choices
Eutrophication often starts with stimulating algal growth
[ Choose ] TRUE FALSE
Eutrophication results in loss of dissolved oxygen from the process of photosynthesis
[ Choose ] TRUE FALSE
It is the decomposition of algae after algal blooms that lead to bacterial growth causing a loss of oxygen
[ Choose ] TRUE FALSE
Eutrophication is a natural process and can occur in the absence of fertilizers
[ Choose ] TRUE FALSE
In Eutrophication, excess nutrients can cause algal blooms. However, what happens when the algae eventually die?
Bacterial – Increase or decrease
Oxygen – Increase or decrease
Why is algae a better source of nutrients than fish?
