Marine ecosystem Essays

organisms are living in a marine ecosystem. For example, an estimated 50-80% of all life on earth is found under the ocean surface. This may be due to the fact the ocean accounts for 99% of Earth’s living space. With so much life and biodiversity going on, there are bound to be problems; problems that can affect the organisms in and out of the water. One of these problems is red tide. Red tide is caused by microscopic, marine algae. Algal blooms occur in freshwater as well as marine environments. In general

Ocean currents and wind currents are a huge part of the systems on earth. They have global impact on our environment and on mankind. There are many currents which all have their own characteristics and effects on different parts of the world. One of the world’s major ocean currents is the Kuroshio Current, a north-eastward flowing current, which flows along Japan and eventually merges with the easterly drift of the north pacific. The current transports warm, tropical water towards the polar region

Plastic : To keep or ban? In the ocean there is a new continent. It’s made up of trash the size of Europe. There is about 100 million tons of trash floating around in the ocean today, states “Are you eating plastic for dinner” a national geographic video. About 70% of that trash are plastic. Plastic is a material that is used in everyday life, but too much of that plastic is not being recycled, about 30%. The other plastic is being pushed into landfills and the ocean The article “Bum Wrap” states

the balance of marine biology. Zebra mussel fertilization occurs in water columns—the area from surface to sediment of a sea, river or lake—because the temperatures of these water columns are ideal environments for reproduction. The problem is that zebra mussels lay over 40,000 eggs in one reproductive cycle “and up to one million in a spawning season” (Benson et al. par. 4). At the rate that they reproduce, zebra mussels can easily outnumber and destroy floral and fauna of marine life where they

Biomes are places that share similar climate and life form. Biomes are also referred to ecosystems. There are five main groups of biomes: forest, desert, grassland, tundra and aquatic. I chose to do aquatic biomes because there are a lot of uses that this particular biome provides. The Aquatic biome covers three quarters of our plant, there is a wide variety of marine wildlife and many different plants, corals and algae. Being one of the largest biomes, the aquatic biome varies in temperature due

kelp. The kelp forests are dense groupings of kelp that form rich underwater ecosystems that a great variety of species depend on, including humans, yet many do not take importance on these endangered forests of the ocean which is why an explanation that illustrates the description, importance, and the threats that kelp forests go through will be given. Kelp forests are important marine ecosystems that thousands of marine species depend on and also serve many important environmental and economic purposes

Loss of biodiversity Introduction Biodiversity is the variability among living organism from all sources, including terrestrial, marine, inter alia, and other aquatic ecosystems and ecological complexes they are part of. they include the diversity within species, between species and ecosystems. Biodiversity also refers to the abundance of different species living within a given region. It showcases the wealth of biological resources available to us. It sustains the natural area that is comprised

biomes are different in several ways, including their distribution, physical characteristics, and ecological functions. The reef biome is a marine biome that is characterized by shallow, sunlit waters, and high levels of biodiversity. Reefs are composed of calcium carbonate skeletons that are secreted by corals, which form the foundation of the reef ecosystem. The reef biome is found in tropical and subtropical waters around the world, primarily in shallow, coastal areas. In contrast to the reef biome

Keystone species are essential elements of ecological communities and have a disproportionate impact on the composition and operation of ecosystems. A keystone species is one that, in relation to its abundance, has an overpowering effect on its surrounding ecosystem. They influence many other organisms in an environment and help to decide the types and quantities of different other species in the community, all of which are essential to sustaining the foundation of an ecological community. The ecology

Biodiversity Biodiversity is the variety of all living organisms in a specific habitat, it is made up with abiotic and biotic factors. Biodiversity gets used to measure the health in a ecosystem. Humans have, over several years, created threats to biodiversity, one of them is overexploitation. Under the impact of biodiversity changes and overfishing by humans, many species have become extinct, which, in the end influences the biodiversity again. Many solutions have been attempted to be created over

over and kill native species. Native species are key parts of the ecosystem. They regulate water absorption, protect against erosion, and protect marine life. The community on Maui feels the negative effects of invasive species taking over the forest. For example, there are water shortages, erosion, landslides, coral bleaching, damages to marine life, and murky water. I feel it is important to maintain our native ecosystem. Therefore, I will be volunteering to first hand alleviate the issues

Introduction Biodiversity plays a key a role in the ecosystem (Mace et al. 2011) and aquatic habitats are the most diverse in the world. The species that inhabit these ecosystems have evolved and developed adaptations over millions of years that have helped them survive. In this lab, we endeavored to gain a deeper understanding of the different variables that determine the species composition of two vastly different aquatic ecosystems in Biscayne Bay. Communities that are more biologically diverse

Introduction of Foreign Species into the Australian Ecosystem B1. Investigate the impact of human activities on the diversity of living things. Describe the impact that this activity has on the environment and species diversity. The early European settlers of Australia during the Imperialism introduced feral animals into Australia for many different reasons without knowing the harmful effects it brings to the ecosystem of their new home. For example, rabbits were introduced in 1859 by English explorers

conservation, however, brings about it a fair share of controversy and concern. Reasons such as introducing an invasive species to a non-native area, negatively altering the ecosystem factors provided by the area, and changing already determined species relationships, are why some scientists reject the idea of relocation. However,

1. What are the two basic components of any ecosystem? • Abiotic – nonliving environment • Biotic – living components SOURCE: Instructional Material 2. What two physical factors determine the type of biome that is present in an area? • Climate • Geography 3. Explain why autotrophs are called producers and heterotrophs are called consumers. • Autotrophs are called producers because they make their own food • Heterotrophs are called consumers because they rely on other organisms for their energy and

separated into the following five levels in ascending order; species, populations, communities, ecosystems, and biomes. The first level of the biosphere are the species, which are individuals who are genetically related and can produce offspring. Examples of species would be alligators,

the first ecologist to use the term “ecosystem” in a scientific publication (Cleveland 2014). In the publication, Tansley defined an ecosystem as “The whole system… including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment” (Ellis 2014). Today, scientists have defined an ecosystem as “a system which is formed when a community of organisms interacts with the environment” (Ecosystem.org). Ecosystems are communities where organisms interact

Ocean Ecosystem There are many limiting factors in a marine ecosystem. These limiting factors interact in many ways to form different features and also affect the marine ecosystem. This paper analyzes the relationship between the temperature of the region and rate of evapotranspiration, the upwelling of water and the speed of wind, the ocean currents and the climate experienced, and nature of rocks and type of features formed. The temperature of the surrounding region in an ocean is very important

Habitats: Place in which an organism ordinarily lives in to survive. Niches: The spot an organism fills in a community/ecosystem. Ecosystem

Estuaries and upper estuarine freshwater are ecosystems which contain zooplankton, phytoplankton, microbes, vertebrates and invertebrates, and in general they are exposed to different freshwater and marine influences (Chen & Stillman, 2012; Cohen, 2000). These waters and especially the upper estuarine freshwater ecosystems are often exposed to changing circumstances like seasonal climate, changing tides, stratification and estuarine circulation (Geyer, Trowbridge, & Bowen, 2000; Goodrich & Blumberg
