Responses

decreased oxygen in the water
decreased oxygen in the water

decreased carbon dioxide in the water
decreased carbon dioxide in the water

increased fish population
increased fish population

increased underwater plant population

Answer 1

- decreased oxygen in the water: Algae blooms can lead to a depletion of oxygen in the water, causing harm to marine life that depends on oxygen for survival. This can result in fish kills and other negative impacts on ocean ecosystems.
- decreased carbon dioxide in the water: Algae blooms can actually increase carbon dioxide levels in the water through the process of photosynthesis, rather than decrease it.
- increased fish population: Algae blooms can actually have a negative impact on fish populations, as decreased oxygen levels and other factors can lead to fish kills.
- increased underwater plant population: Algae blooms can outcompete other underwater plants for resources, leading to a decrease in plant diversity and potentially impacting the overall health of the ecosystem.
