Question

What is a potential consequence of excess phosphorus and nitrogen in an ecosystem?

a) Increased biodiversity
b) Acidification of soil
c) Reduction in algal growth
d) Decreased eutrophication

Answer 1

Excess phosphorus and nitrogen in an ecosystem can lead to eutrophication, which can cause the death of other aquatic organisms and disrupt the balance in aquatic biomes. So, the correct answer is option d.

Step-by-step explanation:

Excess phosphorus and nitrogen in an ecosystem can lead to the overgrowth of algae in bodies of water, causing a process called eutrophication. This overgrowth of algae can clog waterways, block sunlight, and deplete oxygen levels, which can lead to the death of other aquatic organisms such as fish. Additionally, the excess nutrients can run off into waterways from irrigation and rain, causing nutrient pollution and disrupting the balance in aquatic biomes.

So, the correct answer is option d.
