The Coastal Ecosystem of Bay of Bengal - The coastal ecosystem of Bay of Bengal (BOB) is described using a mass-balance model of trophic interactions, in order to understand the effects of Set Bagnet (SBN) on the ecosystem. The BOB model encompassed an area of 24,000 km2 and had 14 functional ecological groups of which 13 were living groups and one dead group (detritus). Result showed that all consumers had ecotrophic efficiency (EE) >0.90 indicated that the consumers were heavily exploited in the system. The fishery was operating at a mean trophic level of 2.45....   [tags: Environment, Ecosystem ] 2658 words

Coral Reefs: A Diverse Ecosystem - Coral reefs are one of the oldest and the most diverse ecosystems in the planet; because of such matter, scientists coined coral reefs as ‘rainforests of the sea. The National Oceanic and Atmospheric Administration or NOAA for short (2008) estimated that about 25% of marine life use coral reefs as safe havens from predators, breeding grounds, and feeding grounds despite the fact that coral reefs only cover a small percentage (estimated about 0.1%) of the world’s oceans. It serves an umbrella specie because it serves both as a habitat and a living, breathing organism for other marine animals to thrive....   [tags: coral reefs, ecosystem, marine life] 811 words

Pollination, Biodiversity & Ecosystem Services - The pollen is constituted by a multitude of microscopic granules contained in the pollen sacs of the anthers of flowers and has the appearance of a powder, coloured differently depending on the flower. These granules are the male reproductive cells of the plant. This powder is easily carried by the wind and can reach the female organs of the flowers, the pistils. The other way of pollination than that of pollen dispersal is the fertilization of flowers, when it is given by bees and other pollinators....   [tags: powder, bees, ecosystems] 1125 words

The Everglades' Ecosystem - ... This meant the once meandering rivers and streams no longer got to filter the fertilizers from the farmers' crops, and were dumped directly into the Everglades. The fertilizers caused algae to grow, and when the algae withered and sunk to the bottom, it caused the oxygen levels to drop. This killed fish and created less of a food source for the animals that ate fish as their primary food source (13-14). The second point of research is about the landscape of the Everglades and how it affects the ecosystem....   [tags: wildlife, park, marshland] 700 words

The Rainforest: More Than an Ecosystem -   An ecosystem is a community of all organisms in a given area, and the physical environment which they interact with. On the land there are terrestrial ecosystems such as forests, grasslands or rain forests; and in the water there are freshwater and marine ecosystems such as lakes and, say, coral reef. The rain forest is an energetic ecosystem. This means that the rain forest vegetation grows quickly and when dead, decomposes extremely quickly. Rain forest biome is very complex. It includes a myriad of different species of plants and animals that are all adapted to rain, and lots of it....   [tags: organisms, physical environment]

However, the New York Times say that the Carp could easily put an end to the $7 million dollar fishing industry in the Great Lakes.

Ecosystem Services: Deforestation and Soil Erosion - According to Mooney and Ehrlich (1997), the idea that human beings depend on natural systems traces back as far as Plato. Plato (c. 400 BC) realised that deforestation could lead to soil erosion and the drying of springs (Daily 2007; Gómez-Baggethun et al., 2009). The first modern publication that addresses this concept is in the book Man and Nature written by George Perkins Marsh dated 1864. Marsh started to realize that the world’s resources were not infinite and that natural systems are important to water, soil, climate, the disposal of waste and pest control....   [tags: environmental science, fresh water]

Considering this quantity of fungal mycelia in the soil, it is easily possible that the whole forest ecosystem might be interconnected by a fungal web called common mycorrhizal network (CMN) (Peter, 2006; Lekberg et al., 2010). The simplest CMN structure consists of one or more mycorrhizal fungi that connect at least two plant root systems.
