Aquatic ecosystem such as the oceans, is a huge reserve for atmospheric CO or carbon monoxide (Aquatic ecosystems: carbon cycle and as atmospheric CO sink). As the aquatic ecosystems are huge reservoirs of flora and fauna, these are often overexploited by the people to satisfy their needs. Industrial fishing that gained preference over the past half-century had alarmingly depleted the highest levels of the aquatic food chain which are the little fishes and organisms (Pauly, et. al.). These small fishes and marine organisms are the preys or food products for the organisms belonging to the higher levels in the aquatic food chain. But multi cultural people and their food habits seems to have taken a toll on this aspect. With the growing love for sea foods in modern times, over fishing of these small creates can harm the larger marine creatures significantly. Terrestrial ecosystem is the one which is found in the land mass and consists of the tundra, the taiga, the temperate deciduous forest, and the grassland (Sheaffer & Moncada, 230).These are the source to different plant and animals. Just like the aquatic form, the terrestrial ecosystem has been over overexploited by man. The trees of the tropical grass lands are cut at a very rapid rate for many activities. The future consequences of thee activities will be that it would harm the global balance and also wipe out many exotic species. One of the exploitation activities seen in the lands is the cutting down of trees for making paper. The cost incurred is high and the revenue generated is also very profitable, similarly, over fishing in the water bodies is a form of exploitation which reduces the number of marine animals. Here too the benefit is in the form of increased revenue for the people. Altering the ecosystems Human activities like cultivation whether on the land or water can change the primary form of the ecosystems. terrestrial ecosystem consists of agricultural land, rain forests etc. cultivation is carried out in these areas because of the easy availability of soil , manures etc. this can harm the natural balance of the ecosystems as with the increase in cultivation, the land will be modified which would also alter the landscape of the nearby areas. The animals living in those areas would be forced to migrate to other areas which would disrupt the food chain in the long run (Environmental Biology – Ecosystems). Similar disruption can be seen in the aquatic bodies too. Overfishing can lead to the depletion of the smaller, marine creatures which would force the larger creatures like the sharks and whales to survive on other forms of nutrients which might not be suitable for the organisms. Prioritization of the conservation efforts in aquatic and terrestrial ecosystems On the basis of the principles mentioned in paper 1, the terrestrial organisms Pronghorns, desert cottontails and Single-leaf Pinyon can be prioritized over the others as these are exotic creatures that survive on dry arid conditions. For the aquatic creatures, Chasmistes cujus I need to be conserved as the number of their family genus is depleting. This is followed by Cui-uis, Curly-leaf pondweed or Potamogeton crispus and The Lahontan cutthroat trout or Oncorhynchus clarki henshawi as it is an endangered species. Both the ecosystems need to be conser ...Download file to see next pagesRead More

...?Bawa, Kamajlit S. and S. Dayanandan. “Global Climate Change and The Tropical Rain Forest” Northeastern Naturalist 6.4 (1999 473-485. This is a journal article that covers the Tropical Rain Forests Biome. The article begins by explaining how incredibly important the genetic density of the tropical rain forests, not just for ecological and conservation purposes, but for humans as well. The authors argue that the genetic diversity of trees, for instance, is “vital for the continued flow of goods and services from forests ecosystems to meet present and human needs” (473). The authors also stress that tropical rain forests have a level of genetic density unseen in other parts of the world, and there are many specific niches...

Aquatic and Terrestrial ecosystems

...? Aquatic and Terrestrial ecosystems Aquatic and Terrestrial ecosystems River systems essentially channel the world’s precipitation into surface water systems like lakes and seas. These river systems provide habitats for a vast range of biota, which often culminate in floodplain wetlands that are also regions of astonishing diversity. River systems are critical to most marine, and coastal environments, organisms and processes. Their fresh waters allow humans to infiltrate and dwell in the world’s most inhabitable regions such as deserts. Rivers are the pathways that exemplify ecological landscapes. The climate, as well as the...

This micro-ecosystem comprises of several biotic and abiotic components which interact in different ways to make the micro-ecosystem self-sustainable. Changes in the macro-ecosystem surrounding a micro-ecosystem can influence the latter including effects on the micro- ecosystem’s capacity to support and maintain a balanced, integrated adaptability to prevailing changes diversity and functional organization (Nadakavukaren, 2011).

...? The Impacts of Oil Spills on Marine and Terrestrial Ecosystems Effects of oil spills on marine andterrestrial ecosystems are long-term, and the deaths caused they these effects are not desirable along with other results in the aftermath of oil spills. However, some other effects are not immediate given that there have a potential effect of polluting the entire surrounding of the marine and terrestrial ecosystems. Moreover, these impacts have remained hidden for a long period and the results have been a disruption of food chain among organisms in the areas where the incidence has occurred. In this case, the paper will focus on discussing effects of oil...

Ecosystems

...Ecosystems part 2 Natural ecosystems supply many resources to human society. These products and processes are known as ecosystem services. There are five categories of service, provisioning, regulating, supporting, cultural and preserving services (Daily, 2000). One such ecosystem is the Greater Yellowstone Ecosystem which provides services from all five categories. One of these categories will be discussed here. 1. What is the ecosystem service The cultural service, in this case the sport fishing of Yellowstone cutthroat trout which are members of the salmon family. 2. What ecosystem provides it The Yellowstone...

Adapting to terrestrial living

...Plant adaptation to terrestrial living Plants have evolved from aquatic life to terrestrial forms; while earlier algae forms could survive only in water and died upon exposure to air, they later evolved into variants that could endure short term water deprivation and exposure to air (Niklas, 253). Further genetic variations led to more and more adaptations that produced the first bona fide plants. One of the first problems terrestrial plants faced was the requirement for mechanical support, since they were no longer supported by water as in aquatic life forms and had to deal with less dense air, which could not support their weight...

Aquatic environmetal toxicology

...Aquatic environmental toxicology Cost-effective estimation of bioaccumulation potential There are various methods of determining the bioaccumulation potential including, laboratory test, field monitoring and use of models. Among the three methods, the most easily and least expensive is the laboratory test. This method is simple in such a way that the organisms are placed in vessels that contain sediments and superimposing water, and then they are allowed to accrue contaminants from the sediments for a specific period of time. Chemical analysis is usually done on the sediments to establish a chemical data that will be used to compare the toxicity of the result with any other result. It can be said that the method is...

Threats to Forest Ecosystems

...to 10% of world’s species. Colombia is blessed with variety of ecosystem that includes rich tropical rain forests, coastal cloud forests and open savannas. The country has 51, 220 species of plants of which 30% are endemic. Only 10% of the country’s area comes under protected areas. Forests in Colombia are under threat of extinction due to human development. As estimated by the UN in 2003 approximately 200,000 hectares of natural forests are lost annually. This figure does not include the 100,000 hectares lost illegally by poor people. Approximately 80% of the country is covered with primary forests and a large portion of it has already been lost. The major reasons of deforestation are agricultural activities, mining,...
