What type of lake is rich in organic matter and vegetation but is oxygen poor?
A eutrophic lake is rich in organic matter and vegetation, leading to poor oxygen levels due to decomposition processes. This can result in algal blooms and a decrease in biodiversity as oxygen levels decline.
A process by which nutrients increase in a lake while oxygen levels decrease as a result of human activity is known as?
Eutrophication
During the process of euthrophication what happens to the oxygen present in a lake?
During eutrophication, excessive nutrient inputs lead to massive algal blooms. As these algae die and decompose, oxygen levels in the lake decrease due to increased microbial activity, which consumes the oxygen. This can result in oxygen depletion, leading to conditions harmful to aquatic life.
How does an algal bloom affects the oxygen levels in a lake ecosystem?
An algal bloom can lead to decreased oxygen levels in a lake ecosystem through a process called eutrophication. As the algae die and decompose, bacteria consume oxygen during the decomposition process, depleting oxygen levels in the water. This decrease in oxygen can harm aquatic organisms that rely on oxygen to survive, resulting in fish kills and disruptions to the ecosystem.
In January the depth of a lake was 944 feet. In August the depth of the lake was 519.2 feet. What is the percentage decrease of the depth of the lake from January to August?
It is a 45% decrease
Describe what you would expect to happen to oxygen levels in the hypolimnion of a lake over the summer months?
I would expect oxygen levels to decrease in the hypolimnion of a lake over the summer months due to reduced mixing with surface waters, increased decomposition of organic matter, and higher water temperatures which lower the solubility of oxygen. This can lead to stratification and potential oxygen depletion in the hypolimnion.
Does you tastebuds decrease as you get older?
Yes
What is oxygen depletion?
Oxygen depletion refers to a situation where there is a significant decrease in the amount of oxygen available in a given environment. This can lead to oxygen levels dropping below what is needed for normal functioning of living organisms, potentially causing harm or death.
What do you call a lake that has no oxygen at the bottom?
Dead lake.
What happen when water evaporates from lake?
Water is transformed in vapors; the volume of lake decrease.
What will increase and decrease respiration?
oxygen
Why does the amount of oxygen in the blood decrease when sleeping?
During sleep, our body's metabolism and oxygen demand decrease. As a result, our breathing rate slows down, leading to a lower intake of oxygen. This reduction in oxygen intake causes a decrease in the amount of oxygen present in the blood.
