Explain how the presence of algae can indicate either pollution or productivity of a body of water?
The presence of excessive algae, known as an algal bloom, can indicate pollution in a body of water due to an excess of nutrients like nitrogen and phosphorus from sources like agricultural runoff and untreated sewage. On the other hand, in healthy ecosystems, algae contribute to the productivity of a body of water by serving as the base of the food chain and producing oxygen through photosynthesis. Monitoring algae levels can help assess the health of aquatic environments.
Which algae is pollution indicator?
Certain species of algae, such as diatoms and filamentous algae, are commonly used as pollution indicators. These algae are sensitive to changes in water quality and can serve as early warning signs of pollution in aquatic ecosystems. Monitoring their abundance and diversity can help assess the health of a water body and the level of pollution present.
Do you find algae all along the river?
Yes, algae can be found all along rivers, particularly in areas where sunlight penetrates the water and nutrients are available. Their presence often varies depending on factors like water temperature, flow rate, and pollution levels. In healthy ecosystems, algae play a crucial role in the food web, but excessive growth can indicate nutrient pollution and lead to harmful algal blooms.
How algae and freshwater shrimps are used to measure pollution in water?
Algae and freshwater shrimp serve as bioindicators for measuring water pollution due to their sensitivity to changes in their environment. Algae can indicate nutrient levels, such as nitrogen and phosphorus, as their growth rates respond to excess nutrients from pollution. Freshwater shrimp, on the other hand, can be assessed for their health and diversity; declines in their population or changes in behavior can signal the presence of toxins or degraded water quality. Together, these organisms help monitor ecosystem health and the impact of human activities on aquatic environments.
What is causing a decrease in algae population?
overfishing, pollution, ect.
How mayfly indicate pollution?
because they are sensitive to pollution and that how you can tell how polluted a river is
Is grass a type of algae?
Yes,it is a type of algae because it is green and it is a type of plant.
What species indicate pollution in fresh water?
Some species that can indicate pollution in fresh water include certain types of algae (e.g. green algae blooms), macroinvertebrates like mayflies and stoneflies that are sensitive to pollution, and certain fish species like carp that can thrive in degraded water conditions. Monitoring the presence and abundance of these species can help determine the level of pollution in a freshwater ecosystem.
Are diatoms a type of algae?
No diatom is not an algae
Why can algae be considered as indicators of pollution as well as productivity?
i dont know, ask someone who does
What type of nutrition does algae have?
Algae have photosynthetic nutrition.
Which type of chemical lead to lack of dissolved oxygen?
Nutrient pollution, specifically excess nutrients like nitrogen and phosphorus, can lead to an overgrowth of algae. When the algae die and decompose, bacteria use up the dissolved oxygen in the water, causing hypoxia or oxygen depletion.
