need to show standing water in order to be a pond? How about a bird bath or dog water dish‚ as both can breed aquatic insects if left undisturbed for a few days? For our purposes‚ we have a number of aquatic systems that hold water all year (in most cases) and are impacted to different degrees by activities on the surrounding landscape. What are a few components of an aquatic ecosystem? pond layers - Like in a forest‚ the top‚ middle‚ and bottom of a pond can be vastly different from each other‚ and

clams‚ mussels‚ and oysters‚ which are filter-feeding animals. These animals consume large quantities of water and filter the food‚ often leaving behind a high concentration of the harmful algae in their system. After a shellfish consumes the algae‚ a human will often consume the shellfish‚ leading to problems. This is why humans are often warned not to consume certain seafood in an area affected by a red tide. Cormorants (large diving birds) and pelicans died in large numbers because they were eating

remains of shellfish such as‚ barnacles‚ mussels‚ periwinkles‚ and other mollusks‚ which imply that these humans were using the sea as a major supply of food needed for their survival . Since‚ some early modern humans in Africa‚ were located in Blombos they had a vast supply of water near them‚ which contained their major food supply of shellfish. 2. One possible cause of the great migration is droughts in Africa which threatened these modern humans extinction. Since‚ they consumed shellfish‚ they

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities.

Sewage can poison shellfish‚ but shellfish can be still alive after that. However‚ people do not have resistance and immunity as good as shellfish. When people eat poisoned shellfish‚ they can get illness called paralytic shellfish poisoning. When people boil the shellfish‚ paralytic shellfish poisoning goes into water because it is soluble in water. However‚ this poison can resist heat and acid‚ so it cannot be marred by other cooking method. When people eat the shellfish‚ the poison is still

grooves divides the body into 2 parts‚ in which its orientation‚ size and shape can be used to indentify them in morphological taxonomy. Toxic dinoflagellates are known to cause diarhetic shellfish poisoning (DSP)‚ paralytic shellfish poisoning (PSP)‚ neurotoxic shellfish poisoning (NSP)‚ and Ciguateria shellfish poisoning (CSP)‚ hepatotoxicity‚ and toxicity to the marine fauna. Thus their bloom is harmfull to the ecosystem and to human health. Dinoflagellates can bloom by the natural means‚ but this

In this research paper‚ readers will be able to know about algal blooms or commonly known as red tide. This is a situation wherein algae reproduce easily because of the chemicals that flows through different bodies of water. Algal bloom is also connected in climate changes we encounter in this century. It’s either the algae reproduce easily by the climate or the algae are having hard times reproducing for the same reason. It can also be observed in aquariums. An experiment is given for the readers

Leaves the victim in a state of paralysis as symptoms progress. Death can result from respiratory failure. Neurotoxic shellfish poisoning (NSP)‚ sickness caused by the result of ingesting shellfish contaminated by brevetoxin. Symptoms include nausea and neurological symptoms like slurred
