Marine Ecosystem - 1607 Words

The earths oceans provide an enormous range of resources and affect the quality of life as we know it. The oceans cover approximately 70 percent of the surface of the earth and have a cyclical effect on weather, e.g. temperature, precipitation and air quality. Regardless of your views on global warming, the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence, emissions of greenhouse gases from human activities are projected to cause significant global climate change during the 21st century. Such climate change will create novel challenges for coastal and marine ecosystems that are already stressed from human†¦show more content†¦However, the total amount of energy in the universe available to do biological work is decreasing over time.This law plays into the fact that energy in life-organisms is decreasing over time. If this were not the case th en, these organisms would live forever. Instead the law is biological creatures are born and they die. Energy can only be transferred. It cannot be created or destroyed. In the marine life-system this is as evident as in any other life-system. Benthos relies on nekton just as much as plankton. They are all locked in a complicated yet simple dance of consumption, reproduction, and death following in decomposition. This can be translated into energy examples such as taking in energy through capturing, transferring energy as in reproduction and dispersing energy back into the general eco system by death. Abiotic factors are elements of an ecosystem that are non-living but still have an impact on the environment. Some examples of abiotic factors that impact the marine ecosystem include: water temperature, sunlight, ocean currents and the salinity of the water. Biotic factors in the marine ecosystem are the living organisms, which include plants and animals. Biological evolution accounts for the diversity of species developed through gradual processes over many generations. Many species develop their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations.

Two different types of rocky shore ecosystem were examined, the rock pool area, and the boulder area. We first examined areas within the rock pool area. The rock pool area has several specific featuresRead MoreEndangered Species Of Marine Ecosystems1616 Words   |  7 Pagesholds in a fishery. This policy will enable controlled fishing (Solliman, 2014). Endangered species of marine ecosystems can also be restored in an artificial way. This is a practice that ensures all species will coexist in many years to come. Through this practice different species are introduced in a new habitat. Here they are mingled with native species. This enables a specific ecosystem to have variety of different species. It is this practice that ensures predators do not run out of food.Read MoreHealth And Sustainability Of Marine Ecosystem Degradation1026 Words   |  5 Pagesto â€Å"conserve and sustainably use the oceans, seas and marine resources for sustainable development.† Targets 14.1, 14.2, 14.3, 14.4, 14.5 and 14.a, aim to improve the health and sustainability of marine ecosystems by a specified date, and avoid adverse impacts to the environment by addressing specific kinds of marine pollution. These are measurable in so far that it is scientifically possible to quantify nutrient pollution, ocean acidity, marine debris, biodiversity etc. , across space and time, asRead MorePlastic And Its Effects On The Marine Ecosystem2990 Words   |  12 Pagesamount of space and poisons animals. The overflow of plastic eventually makes its way into the ocean and is affecting marine life at an alarming rate. Plastic debris pollutes oceans all over the world as it breaks down into smaller pieces and are ingested by a large range of species. Animals exposed eat the plastic products and it causes health problems throughout the marine ecosystem. Some humans rely on these animals for food without knowing that they have been exposed to toxic products. The smallestRead MoreThe Effects Of Ocean Pollution On The Marine Ecosystem1517 Words   |  7 Pages Ocean pollution comes in many forms with each having some sort of effect on the marine ecosystem. Ocean pollution is destroying earth s waters, because its killing populations of organisms in the water all over the ocean, Its destroying coral reefs and water is being contaminated with oil,garbage and chemicals.Which in turn is destroying organisms all over the ocean. For the purpose of this paper, it will be logical to categorize these pollutants into three main areas; garbage, chemical, and noiseRead MoreMarine Ecosystem Causes of Degradation and Case Studywhat Is the Marine Ecosystem?

Marine ecosystems are among the largest of Earths aquatic ecosystems. It covers almost 70% of the earth’s surface. They include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content. â€Æ' Why is the Marine Ecosystem important? Marine ecosystems are very important in to the overall health of both marine and terrestrialRead MoreImpact Of Overfishing On Marine Ecosystems And Human Culture1724 Words   |  7 PagesIntroduction Overfishing occurs when fish are being caught faster than they can reproduce and replace themselves (Lee and Safina, 1995, pg.5). It greatly affects biodiversity of marine ecosystems and human culture. Impacts of Overfishing Overfishing can impact marine ecosystems and communities that rely heavily on marine mammals. Large reductions in population sizes of marketable fish species caught yearly may significantly create economic stress within fishing communities, especially if they mainlyRead MoreHumans Are Wiping Out the Marine Ecosystem Essay771 Words   |  4 PagesOur ecosystem is in danger. Fish, corals, octopuses, turtles, and even whales are dying. One may ask why: humans. Humans are wiping out multiple ecosystems on a daily basis. If this atrocious rate of marine life genocide continues, the human race probably won’t be able to have fish on their dinner plates in approximately a hundred years. The water is murky, and life is fading away. Several factors act as a cause for this catastrophe. For example, the annihilation of marine organisms is kindled byRead MoreThe Negative Effects of Humans and Nature on Florida’s Marine Ecosystems2047 Words   |  9 Pagesone large marine ecosyste m. Florida is one big sand peninsula located below the 40th longitudinal North American line. Three bodies of salt water (Gulf of Mexico, Strait of Florida and Atlantic Ocean) surround three out of four directions of Florida. Man-made canals, natural lakes, rivers and estuaries are confined within the State of Florida’s physical boundaries. All of these form an interlocking system of waterways that impact the interconnected marine environment (marine ecosystem).
