Question

Which of the following best describes the effects of water pollution on aquatic ecosystems? It can result in fishkill and restrictions on human conception.

1) Decreased biodiversity and loss of habitat
2) Increased algal blooms and oxygen depletion
3) Contamination of drinking water sources
4) All of the above

Answer 1

Water pollution has various effects on aquatic ecosystems, including decreased biodiversity, increased algal blooms and oxygen depletion, and contamination of drinking water sources.

Step-by-step explanation:

Water pollution has various effects on aquatic ecosystems. Some of the effects include:

1. Decreased biodiversity and loss of habitat: Water pollution can lead to the destruction of habitats, resulting in a decrease in the variety of species that can survive in an ecosystem.
2. Increased algal blooms and oxygen depletion: Excess nutrients in the water, such as from fertilizer runoff, can cause algal blooms. These blooms can deplete the oxygen in the water, leading to the death of fish and other organisms.
3. Contamination of drinking water sources: Water pollution can contaminate sources of drinking water, making it unsafe for human consumption.

Therefore, the correct answer is option 4) All of the above, as all of these effects are potential consequences of water pollution on aquatic ecosystems.
