Lentic vs lotic system
A lentic system is a large body of motionless and still water like a pond or lake.
A lotic system is a body of water that is constantly in motion like a river or a stream.
Eutrophic vs Oligotrophic Systems
eutrophic systems are rich in organic and mineral nutrients and supporting an abundant amount of plant life, which in the process of decaying organisms and the oxygen supply for animal life. Compare oligotrophic
An oligotrophic system is a body of water that is very low in nutrients and plant life also it doesn't have much oxygen so photosynthesis very rarely happens which is why there isn't many plants.

limnology
hypolimnion- the lower layer of water in a stratified lake, typically cooler than the water above and relatively stagnant.
epilimnion- the upper most layer of water in a stratified lake.
thermoclines- a steep temperature gradient in a body of water such as a lake, marked by a layer above and below which the water is at different temperatures.

Trophogenic Zone vs Tropholytic Zone
Trophogenic zone- also known as the photic zone. this zone is the highest zone of the water where photosynthesis takes place. which allows plants to grow and move around. algae is one of the common plants that occur from photosynthesis.
Tropholytic zone- this zone is at the bottom of the of the pond and has almost no light so photosynthesis so there is alomt no plant life in this zone.
Overturn
Overturn is the process of mixing the top and bottom regions of a stratified body of water. In other words, you are mixing up the nutrients trapped in the bottom layer. This process is started by wind or rain or anything that causes water to mix all it's nutrients. overturn is likely to occur in warmer seasons like spring or summer.
Water quality
The pH of water is measuring the acidity or alkalinity of the water. sea water the pH is 8.3, water also needs steady levels of dissolved oxygen. the common levels of dissolved oxygen can range from .0 to 18mg. in drinking water if you have nitrate it can be threatening to your health.
