Answer:

Cause:

Animals waste appears in the water supply

Fertilizer is applied

Effect:

Water is unfit for aquatic life

Algal blooms occur

Explanation:

When fertilizer is added in water ,then it leads to the problem of eutrophication in which algal boom occurs due nutrient enrichment of water. The excessive growth of water plants use the dissolved oxygen and leave oxygen devoid water for other aquatic species. These aquatic species ultimately die due to lack of oxygen.  

Animal waste causes increase of chemical elements such as nitrogen, phosphorus and potassium and render water unfit for any life form

The increase of nutrients in the water supply. Cause animal waste appears in the water supply and fertilizer is applied, and the effect is the water is unsuitable for aquatic life and algae blooms occur.

What is water eutrophication?

Eutrophication consists of the increase of nutrients, such as nitrogen and phosphorus, in an aquatic ecosystem, which leads to increased productivity and, consequently, changes in this entire ecosystem. The increase in productivity is mainly caused by excessive algal blooms.

With this information, we can conclude that the increase of nutrients in the water supply. Cause animal waste appears in the water supply and fertilizer is applied, and the effect is the water is unsuitable for aquatic life and algae blooms occur.
