Explain how eutrophication can change an aquatic ecosystem into a land ecosystem

1 answer:

7 0

Eutrophication (the overenrichment of aquatic ecosystems with nutrients leading to algal blooms and anoxic events) is a persistent condition of surface waters and a widespread environmental problem. Some lakes have recovered after sources of nutrients were reduced. In others, recycling of phosphorus from sediments enriched by years of high nutrient inputs causes lakes to remain Eutrophic even after external inputs of phosphorus are decreased. Slow flux of phosphorus from Overfertilized soils may be even more important for maintaining eutrophication of lakes in agricultural regions. This type of Eutrophication is not reversible unless there are substantial changes in soil management. Technologies for rapidly reducing phosphorus content of over-enriched soils, or reducing erosion rates, are needed to improve water quality.

Naily [24]

be slower at absorbing nutrients than the other cell

Explanation:

The cell without the microvilli will be expected to have as slower absorption rate of nutrient than the other cell.

Microvilli are finger-like projections from the surface of the cell.
The structure has a large surface area to volume ratio which allows for nutrient to be absorbed easily.
These structures are very important during the absorption of digested food in cells.

Cells without this structure will not absorb food faster.

Why is so much energy "lost" between trophic levels?

BabaBlast [244]

Answer:

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat.

Explanation:

When the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is

blsea [12.9K]

Answer:

Osmosis and facilitated diffusion are two forms of passive transport that are integral to cellular transport mechanisms.

Explanation:

Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.

Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.

Across plasma membranes as a form of passive transport in cells, substances move via:

osmosis - water molecules readily pass through the membrane; the molecules move from high concentration regions to low concentration regions at will through the membrane- they move down their concentration gradient
facilitated diffusion - channel proteins allow charged ions to move across the membrane. Sodium ions are able to pass freely through specialized sodium channel pores into some cells. These channels always remain open- the ions move down their concentration gradient.
