ateo goes to his doctor after experiencing discomfort for a few days. Following tests and an examination, the doctor tells Mateo

that his body is unable to get rid of waste products, and their high levels are the reason for his discomfort. Mateo is most probably suffering from a disease that’s affecting his body’s ability to excrete waste products. He may have to take medication. If his condition worsens, he might have to regularly undergo to filter the waste products from his blood. NextReset

This is a case of acute or chronic (or acute on chronic) kidney disease. Mateo should take diuretics or drugs that induce tubular secretion and/or water excretion and therefore urination. If kidney disease worsens, the patient will undergo filtration of waste products from his blood or this is called hemodialysis. There is another way of filtering waste products using the fluid in the peritoneum called peritoneal dialysis. Other complications of chronic kidney disease is anemia as erythropoeitin (functions to signal the production of red blood cells) is produced in the kidneys.

I kept a record of the sources with the extracted information. I have the links if you would like them.

<u>Hydro-international article: Benthos, Inc.</u>

Benthos was founded by Samuel O. Raymond.  

He created an innovative company in marine technology which has positively impacted the field for over four decades.

It manufactures a variety of oceanographic equipment, including flotation devices; hydrophones for locating mining sites, tracking boats, and research for marine biology; and modems, which are used to communicate information wirelessly underwater.

For much of the company's lifetime, it supplied underwater equipment to the military, the government, and for research.

<u>Smithsonian Magazine: 14 fun facts about marine bristle worms</u>

Polychaete worms are a diverse class of animals with at least 10,000 species.  

They are characterized by a head and a tail, and a pair of bristled "legs", called parapodia, for each segment of their body. They are typically bioluminescent, meaning they have the natural ability to glow.

Due to their effective adaptation, they can live in any marine habitat (including coral reefs, hydrothermal vents, or simply out in the open ocean) and have survived the five mass extinctions since 500 million years ago.

<u>National Ocean Service: What is a bivalve mollusk?</u>

Bivalves are mollusks with a two-part hinged shell to cover a soft invertebrate. They breathe and eat using gills.

Their organ, the mantle, produces calcium carbonate which causes the shell to grow with the organism.

They have important roles of being prey for predators, filtering water, and acting as a habitat in aquatic ecosystems.

These mollusks can live in any of the five oceans, whether it be the frozen Arctic or the hydrothermal vents in the Pacific.

There are over 9000 species.

<u>Marine Education Society of Australasia: Echinoderms</u>

Echinoderms are characterized by radial symmetry, having multiple of five arms, a calcium carbonate shell, and an outer layer of skin that maintains the skeleton.

They are found on the sea floor and include starfish, sea cucumbers and sea urchins.

They have the ability to hunt prey larger than their mouths due to their ability to eat from their stomachs. They detect food through a senstitivty to chemicals, although they lack any brains.

There are over 7000 species.

<u>Thoughtco: Sea Squirts</u>

Sea Squirts, scientifically tunicates or ascidans, are a class in the animal kingdom with over 2000 species.

They were given this name for their ability to contract and squirt water.  

They do this using the inhalant and exhalant siphons, which are also used for eating and excreting waste.

They live in subtidal locations while attached to shells, rocks, piers and boat hulls.

Sea Squirts may live in colonies or individually. Colonies are created when they reproduce by budding, or when a new animal grows off of the original.

<u>National Geographic.com: Sea Anemones</u>

Sea anemones are an invertebrate which have stinging and venom-filled tentacles, called polyps, to hunt passing fish.

They tentacles surround a central mouth and inject a paralyzing substance into its prey, before guiding them into the mouth.

Apart from hunting, they also eat leftovers from clownfish, who are immune to the anemone because they are covered with a mucus and live within the polyps.

They live attached to rocks on the seafloor and coral reefs, usually in tropical waters.

There are over 1000 species.

<u>Conclusions or Summary:</u>

The marine technology company Benthos led to the discovery or further information about these animals because it provided equipment to researchers.

All of these organisms are animals and diverse with thousands of species in each of these common names.

They are adaptive and can generally live and thrive in a variety of habitats, whether the difference be in surface material or climate.

What happens to a ecosystems food chain if the concentration pollutants move up.
Furkat [3]
<span><span>Producers: Plants are producers because they make usable energy from light.  They turn sunlight, carbon dioxide and water into sugar energy.  Producers are the foundation of the food web, because they provide the base energy needed by all wildlife.</span><span><span>Primary Consumers: </span>Herbivores are primary consumers, because they receive their energy directly from plants. </span><span><span>Secondary Consumers: </span>Carnivores are secondary consumers, because they receive their energy by eating primary consumers.  Secondary consumers are predators.  An omnivore acts as both a primary and secondary consumer, because omnivores eat both animals and plants. </span><span>Decomposer:  Decomposers get energy by breaking down dead plants and animals.  They are extremely important, because decomposers convert dead matter into energy and release nutrients that can be added back to soils and ecosystems.</span></span>


<span>What is a Food Web?
</span>A <span>food web </span>is a diagram displaying how all the producers, decomposers and primary and secondary consumers interact in an ecosystem.  It shows how energy is transferred between species. 

A food web can be very simple - with one producer, consumer and decomposer- or a food web can be extremely complicated.  A food web of an entire woodland ecosystem becomes complex when you include every species from plants to insects and mammals. 


There Is More to a Food Web than Energy

When animals eat their prey, they consume more than just energy.  They also absorb all the chemicals and nutrients inside the prey.  For example, when you eat a banana you get energy from the banana, as well as the added benefits of potassium and vitamin A. 

Sometimes animals ingest pollutants that can become stored in their fat and tissues.  Human-caused pollution has added heavy metals, oil, and <span>industrial and pharmaceutical chemicals </span>to the environment.  Plants, fish and other species absorb these toxins, and as they are eaten by predators, the toxins are then absorbed into the predators’ tissues.  As the chain of predator and prey continues up the food web the toxins become more concentrated and move higher and higher up the food web.  The pollutants can have a disastrous effect on the food web and potentially kill species.


What happens when a Chemical is Added to the Food Web? 
To explain the true impacts of chemicals on the food web, we’re going to use the real world example of mercury poisoning. 

Coal-fired power plants burn coal and release mercury into the atmosphere as a byproduct.  Over time, mercury falls to Earth through rain, snow and natural settling.  Rain carries the mercury to streams and rivers and it eventually settles in lakes and ponds. 

After mercury enters lakes and ponds, bacteria transform mercury into a more easily absorbed toxic substance called methylmercury.  Aquatic plants, bacteria and plankton absorb methylmercury from the surrounding water. 

It’s at this point that mercury becomes added to the food web.  Eventually, the contaminated plants, bacteria and plankton will be eaten by predators, such as fish.  The methylmercury toxins will move into the tissues of the fish and poison a new level of the food web. 


Magnifying Up the Food Web 
Individual plants, plankton and bacteria only have a small amount of methylmercury.  The problem begins at the next level of the food web.  Fish don’t eat just one plankton or plant – they can eat hundreds or thousands of them!  All the mercury in each of the plankton or plants has now been eaten by a fish and absorbed into the fat and tissues.  After eating 100 plankton, the methylmercury in the fish is now 100 times what it was in the plankton! 

It doesn’t stop there.  The higher and higher up the food chain you go, the more food is necessary to maintain energy and activity. 

<span>If a small fish eats 50 mercury contaminated plants.And a large fish eats 100 small fishAnd an eagle eats 100 large fish.</span>

50X100X100 = 500,000  The concentration of mercury in the eagle is 500,000 times larger than it was in the plankton!!

The process that causes the concentration of a substance to increase as it moves up the food web is called bioaccumulation.  Methylmercury is a famous example of bioaccumulation, because mercury poisoning causes neurological disorders, reduced reproduction and even death in raptors and mammals.  People are susceptible to mercury poisoning by eating too much contaminated fish.  

Study the diagram to see how mercury bioaccumulates up this common food web.
