Consider the following statements about the effects of eutrophication...
Effects of Eutrophication:
1. Decreased Turbidity:
- Eutrophication leads to the growth of algae and other aquatic plants, which can decrease the turbidity of water bodies.
- This can affect navigation and reduce the amount of light that penetrates the water, which can harm aquatic plants and animals.
2. Increased biomass of inedible toxic phytoplankton:
- Eutrophication can lead to the growth of inedible toxic phytoplankton, which can be harmful to aquatic organisms and humans.
- These phytoplankton can produce toxins that can cause fish kills, shellfish poisoning, and even illness in humans who consume contaminated seafood.
3. Increase in the bloom of gelatinous zooplankton:
- Eutrophication can also lead to the growth of gelatinous zooplankton, such as jellyfish.
- These blooms can be harmful to fish and other aquatic organisms by competing for resources, and can even cause fish kills.
4. Increase the biomass of benthic and epiphytic algae:
- Eutrophication can lead to an increase in the biomass of benthic and epiphytic algae.
- This can lead to the smothering of other aquatic plants, which can harm fish and other aquatic organisms that rely on these plants for food and habitat.
Therefore, the correct answer is option 'B' as all the given statements except statement 1 are correct.
1. Decreased Turbidity:
- Eutrophication leads to the growth of algae and other aquatic plants, which can decrease the turbidity of water bodies.
- This can affect navigation and reduce the amount of light that penetrates the water, which can harm aquatic plants and animals.
2. Increased biomass of inedible toxic phytoplankton:
- Eutrophication can lead to the growth of inedible toxic phytoplankton, which can be harmful to aquatic organisms and humans.
- These phytoplankton can produce toxins that can cause fish kills, shellfish poisoning, and even illness in humans who consume contaminated seafood.
3. Increase in the bloom of gelatinous zooplankton:
- Eutrophication can also lead to the growth of gelatinous zooplankton, such as jellyfish.
- These blooms can be harmful to fish and other aquatic organisms by competing for resources, and can even cause fish kills.
4. Increase the biomass of benthic and epiphytic algae:
- Eutrophication can lead to an increase in the biomass of benthic and epiphytic algae.
- This can lead to the smothering of other aquatic plants, which can harm fish and other aquatic organisms that rely on these plants for food and habitat.
Therefore, the correct answer is option 'B' as all the given statements except statement 1 are correct.

Consider the following statements about the effects of eutrophication...
- Eutrophication eventually creates a detritus layer in the ponds & lakes and produces a successively shallower depth of surface water.
- Eutrophication may cause the ecosystem to become competitive by transforming the normal limiting nutrient to an abundant level. This causes shifting in species composition of ecosystem Toxicity.
- A decrease in water transparency and increased turbidity. • Affects navigation due to increased turbidity.
- Increased biomass of inedible toxic phytoplankton.
- Increase in the bloom of gelatinous zooplankton
- Increased biomass of benthic and epiphytic algae
- Unsuitable for aesthetic recreation, and reduction in the value of water body
