Respiration.

Correct! Wrong!

Aquatic ecosystems require dissolved oxygen removal. Hypoxia (low oxygen levels) caused by pollution, nutrient enrichment, or other factors can harm aquatic life.

"High productivity" in a shoreline area with grasses, sedges, and plants.

Correct! Wrong!

The nearshore region of a body of water, which includes the shallow waters adjacent to the shoreline, is referred to as the littoral zone. The growth of aquatic plants including grasses, sedges, and other vegetation is supported by this zone's high productivity. Plants in the littoral zone provide habitats, food sources, and shelter for a variety of aquatic creatures, which benefits the health of the ecosystem as a whole.

colder water in the bottom section.

Correct! Wrong!

Hypolimnion is a stratified lake or reservoir's cooler, deeper water. Temperature and density divide the water column in a thermally stratified lake.

-Flows 30 to 90% of the year -Absence of water pools in dry conditions -Mostly brown soils with occasional grey - Blue lines divided by 3 dots on maps.

Correct! Wrong!

The information given describes traits connected to sporadic streams or watercourses.

The degree of water clarity

Correct! Wrong!

Turbidity is the term used to describe a fluid's cloudiness or haziness, which is brought on by numerous small particles that are typically unseen to the unaided eye. Turbidity is a term used to describe how much suspended debris, including silt, clay, organic matter, and microscopic creatures, has an impact on the purity of water. These particles have the ability to scatter and absorb light, decreasing the water's transparency and impairing its purity.

They assist in balancing it out. They reduce nutrient burden if it is high. They contribute to raising nutrient load when it is low.

Correct! Wrong!

The ability of beavers to build dams, produce ponds, and wetland ecosystems is well known. The dynamics of nutrient input and output in aquatic environments may be significantly impacted by these activities. Beavers make ponds when they construct dams, which are capable of capturing and holding sediments, organic debris, and nutrients. This may result in a rise in the productivity and availability of nutrients in the water and the surrounding ecosystem.

It is the power needed to heat one gram of water by one degree Celsius. known as a calorie as well.

Correct! Wrong!

Heat capacity is the energy needed to raise a substance's temperature. It is the energy required to raise one gram of a substance by one degree Celsius (or one Kelvin). J/°C and cal/°C are common heat capacity units.

"Light Compensation Point: An area of water where light intensity is 1% of surface intensity. Photosynthesis is equal to respiration."

Correct! Wrong!

The statement accurately describes the aquatic Light Compensation Point (LCP).

"Floating AVP's Open water"

Correct! Wrong!

The Limnetic Zone of a body of water is described by the phrase "Floating AVP's Open water."

More silt equates to greater density and conductivity.

Correct! Wrong!

The statement "More silt equals more density and conductivity" alludes to the connection between the electrical conductivity and density of water.

Profundal Littoral Limnetic

Correct! Wrong!

Lakes and ponds have "profundal," "littoral," and "limnetic" zones. Depth, light, and biological activity define each zone.

Natural -Sulfur-based (from coal?) -Acid rain's gypsum can be used to make sheetrock.

Correct! Wrong!

Acid rain is any type of precipitation, including rain, snow, and fog, that has high concentrations of acidic compounds, especially nitric acid and sulfuric acid. When sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere from a variety of sources, such as the burning of fossil fuels (such as coal) and industrial operations, these acids are created.

"When something works to maintain the biotic community's integrity, stability, and beauty, it is doing the right thing. When it tends in the wrong direction, it is wrong."

Correct! Wrong!

The claim "Maintaining the biotic community's integrity, stability, and beauty is right. It's wrong when it goes wrong "American ecologist, conservationist, and author Aldo Leopold said. Leopold's quote shows his ethical view of environmental conservation and ecosystem health.

Due to shared electrons, this link is strong.

Correct! Wrong!

Atoms share electrons through covalent bonding to establish a stable electron configuration. Two or more atoms share electrons at their outermost energy levels to fill their electron shells in a covalent link. Sharing electrons bonds atoms into molecules. Covalent bonds form stable compounds because electrons are shared.

between water molecules that has a weak electrostatic connection.

Correct! Wrong!

A weak chemical bond forms between a hydrogen atom of one molecule and a highly electronegative atom (usually oxygen, nitrogen, or fluorine) of another.
The partially positive hydrogen atom attracts the partially negative atom it's bonded to electrostatically.

-Deep water — Lower temperatures — Lower DO — Scavengers — Iron reduction and mercury.

Correct! Wrong!

Lakes and ponds' deep, open-water profundal zones are usually out of sunlight. The profundal zone has deeper water, lower temperatures, and lower DO levels than the littoral and limnetic zones. Reduced sunlight penetration limits photosynthesis, lowering DO concentrations. This zone has more scavengers and low-light creatures.
