The statement addition of harmful substances to the environment is called eutrophication. addition of harmful substances to the environment is called eutrophication is false.
The statement provided is false. Eutrophication refers to the process by which a water body becomes overly enriched with nutrients, leading to excessive growth of algae and other aquatic plants.
While it is true that the addition of substances, particularly nutrients like nitrogen and phosphorus, plays a significant role in eutrophication, the term itself does not specifically refer to the addition of harmful substances.
Eutrophication typically occurs when there is an excess of nutrients, often originating from human activities such as agricultural runoff, sewage discharge, or the use of fertilizers.
These nutrients act as fertilizers for algae and other plant life in aquatic ecosystems, promoting their rapid growth.
As a result, the balance of the ecosystem is disrupted, leading to negative environmental consequences.
The excess growth of algae can lead to the formation of algal blooms, which, when they die and decompose, consume oxygen in the water.
This can result in oxygen depletion, negatively impacting fish and other aquatic organisms.
Eutrophication can also lead to changes in water quality, including increased turbidity and the production of harmful toxins by certain algae species.
While the addition of substances to the environment, especially nutrients, is associated with eutrophication, the term itself does not encompass all harmful substances added to the environment.
