Aquatic ecosystem

Pollution Effects on Pelagic and Benthic Areas of the Ocean Biodiversity refers the existing variations present which form an ecosystem enabling human survival. However, the alteration of the world habitat has caused a shift in biodiversity. The role of ecologists is to ensure that there is no extinction of various species in the world due to reckless human behaviour. The maritime environment is among the worst hit areas as human activity creates an imbalance in the water levels. Factors such as

The Impact of Humans on the Biological Diversity of Natural Ecosystems Introduction Since humans have come into existence they have always been a cause of change of whatever natural areas they inhabit along with the living organisms of those natural areas. The different types of organisms such as plants, animals, and microorganisms that inhabit these areas are known as biological diversity or biodiversity. (USEPA 2010 ) Biological diversity can be affected by many different things, climate change

Part A: Ecosystem Profile On the 10th and 11th of August, Year 11 Biology students from Trinity Lutheran College went on a fieldwork excursion to monitor the quality of water in the surrounding ecosystems of 3 lakes in the Gold Coast region. Aquatic ecosystems are an integral part of our environment and play an important role in maintaining the quality of water. The quality of water is important in lakes because it doesn’t just protect the health of the public but it also provides ecosystem habitats

species or human needs. If a lot of excessive nutrients enter the water, the water quality will lead to water pollution. Water is contaminated by contaminants and pesticides which are used to measure the water quality. Drinking water and the health of ecosystems are some things included in the water quality. Contaminants and pesticides are used to measure the water quality. Dissolved oxygen, the amount of bacteria, and the amount of salt contained in the water are also ways that water quality is measured

An invasive species has entered Maryland’s waters and threatens to dramatically alter the balance of the aquatic ecosystem. The Northern Snakehead fish, native to Asia and Africa, is a voracious predator, competing with native fish at all stages of its life. The juveniles will consume zooplankton, insect larvae, small crustaceans and other fry fish. Adults eat fish, crustaceans, frogs, small reptiles and even birds and mammals. Snakeheads aggressively protect their young. They are also air-breathers

Around the world there are extensive river ecosystems and many different kind of animals that inhabit them. Fish are one of the most available animal species in a river ecosystem. Different fish species live in different places of a river environment. Salmon and trout often prefer the oxygen rich, fast flowing rivers, where pike, walleye and are more likely found in silty areas that have been a part of Eutrophication where oxygen is less abundant. fish are an excellent indicator for water quality

law of ecology states, “Everything is connected to everything else”. Everything within the ecosystem has a responsibility to maintain the balance of the ecosystem in order for living things to survive. The ecosphere is a habitat to numerous of living organisms. It is very complex and interconnected in many ways. Commoner explains how the ecosphere produces organic waste that nourishes microorganisms and aquatic plants. The plants are able to produce oxygen into the environment by photosynthesis.

area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms. Eurasian milfoil or Myriophyllum spicatum is an aquatic invasive plant that can be found throughout the Chicagoland area and in surrounding bodies of water. This plant can be a hinderance to swimming, boating, and fishing because of their

beholder: Do biological invasions impact ecosystems on a functional level? Biological invasions are generally considered an environmental threat, out competing native species and increasing community homogenisation. Importantly though, invasive species also alter ecosystems, yet little research has focused on whether invasions are a threat to their functioning or services. This encompasses two main debates: determining whether invasive species alter ecosystem functioning and, if they do, whether these

the health of an aquatic ecosystem that consisted of ghost shrimp, Malaysian trumpet snails, and elodea. The organisms were added to mason jars filled with water, along with varying amounts of water soluble fertilizer, and placed in a well-lit, temperate environment and monitored daily using qualitative observations and with readings from a dissolved oxygen probe and test kit. The hypothesis of the experiment that stated that if 187.5 grams of fertilizer is added to the ecosystem, then all of the
